>> Yeah, it's pretty popular (even if the kind I write isn't that popular).<<

What kind do you write?

>> I agree, every prompt I have fit both original and fandom works (the same goes for my whump prompts). <<

Whump is also enormously popular and would make a great topic. We have hurt/comfort prompt lists but you could also write new prompts.

>>I have some. I tried to host a kinktober and a A/B/O week on my Tumblr. It failed spectacularly. Not sure how much because the blog is small, or the promots were bad, or I'm just bad at promoting it. So having prompts isn't an issue.<<

Bummer. If you're concerned about prompt quality, you could ask experienced hosts to look at your list.

>>Yeah, yeah, I think making a fest only for original work would be unrealistic. I'll ask.<<

You can also mention in any fest that original work is encouraged and/or create a challenge for it.

>> I'll think about it. Maybe I'll aim for August if I get the courage to actually try hosting something.<<

Think it over. I hope you decide to host eventually. It's a lot of fun, and we have a lively crowd here -- there are multiple folks who play almost every month, or at least try to.
