Seems shipshape too me!

I've lived in a country that did away with the penny. It was magical But I guess, to each their own.

The biggest thing imo is that the verse needs to have at least an easily-accessible vaguely-dedicated Bible of important information. I'd love to write more in-canon work, but I struggle to even know the names & domains of the greater demons or the relative technological level of the world, let alone finer details.

The two scales listed are solid, although I'd tweak the mental one more to focus on intensity and not personality. Like, when I'm looking for fics(I can almost assure you I'm the person who prefers the lightest works here), it wouldn't matter if the protagonist became a different person if they still retained their humanity.

Like 1 imagine would be little change, 2 would be have identity changes but not otherwise 'normal'(any sort of basic genderswap would go here), 3 is when things start getting 'bestial' and bordering on whether they have humanity, 4 would be more subdued sex beast(for a common example, when someone turns into a mindless pet), and 5 would be pure there's-nothing-left-except-burning lust(any sort of story where someone becomes nothing but a pile of genitals).

I don't really think you need an list of basic transformations though. Anyone actually interested in writing here will have an idea/s already in-mind, so it won't really matter overall.

In any case, the other biggest issue with introducing people to this community is how hardcore it is. Obviously this is kind of baked into the fetish but there's so much more that can be done besides turning characters into nearly-inhuman sex beasts.

Also, there's this community's flagrant masculine-centric homoeroticism. Like, I'm not really complaining because I'll never write something that doesn't involve girl-girl dynamics; but the number of stories involving female-identified characters turning into ridiculous hypermasculine caricatures or mindless sex beasts far exceeds the opposite. Hell, there's a literal sub-setting completely dedicated to female-to-male transformation.

Anyways, in terms of marketing I don't know how much can be done in the first place. What got me into this stuff was seeing one of demon-man's old comics(the one about the mother and son who turn into the two-headed feminine sex snake thing) posted on /d/, and I would imagine most people found Belial during the 'Golden Age' through similar means. Since most of the artists have circled the wagons and mostly not made anything with wider appeal(two-headed sex snake=bizarre but still retaining enough sexuality to be interesting to fantasize about, a giant hairy anus with legs=not so much), that avenue has been mostly closed.

I think a series of lighter, less-intricate stories could be worth looking into. I know I'd be willing to contribute to that if there was a concerted effort or contest.

Anyways, I forgot where I was going with all this so I'll stop here.

I feel the same way as Flicker and Wexort, although I am aware of the fetishes that have become prevailing in the current state of a number of stories here, I haven't ever been a fan of TF's beyond the odd anthropomorphism, Egyptian God type stuff, MtF/FtM, and a bit of Sub/Dom stuff. Major mental changes (IQ changes, animalistic behavior, or complete loss of self) have been a turn off for me. Physical changes even into animals have been fine but the sexual side of things was far less interesting than some of the amazing stories.

On another note, I don't think a numeric grading system is going to work. It creates too much of a burden on people to conform to what is frankly an unnatural set of rules. It would just be better to stick with keywords and tags like the rest of the internet. After all, people are interested in TOPICS, not NUMBERS. Say a story involves transgender with a total mental gender switch. People would see "mental 3/5" and think, What the fuck is that supposed to mean? Especially when there are so many different types of mental transformations within many different contexts that ranking them becomes meaningless. And what if the mental switch is something that happens over time as a natural course of events post-transformation? Do you throw more numbers to confuse readers with?

A number system would also not account for chronology. What if a transformation happens in stages, or a different TF happens everyday with resets? You'd end up with a bunch of numbers that just lose all meaning. An example would be Arania's animal transformation sequences. I don't care for full animal TFs, but I do care for the anthro midpoints. So you ask anyone, would they prefer to see:
Human --> Anthro --> Animal
or
Body 0/5 --> 3/5 --> 5/5 ?

So let's just do away with any attempts at ranking/numerization. It doesn't work for what is essentially nominal in the first place, it's arbitrary, it's vague, it creates too much work, it fails to include context, and it doesn't convey any actual information to readers. At least not unless you force readers to understand your system at which point you have already asked too much of them.

Just straight up tell readers in words what your story includes.

I don't mean to offend anyone who proposed this system. I know you mean well. I just write my best using a cynical, critical tone, and this numerical system just didn't sit right with me. Had to let it brew over for a couple of days before I could really get at what was bothering me.
