As someone who occasionally write tales about yukkuri, I'm fascinated by the fact that every day there's a new anko uploaded to futaba.
Of course, one of the reasons behind this is that there are a lot more people than here, but still while looking at new stories (not really reading them... many are still too much for me), I also checked out the uploading and reader system.
It's basically a form that allows you to submit your story anonymously, with a bunch of convenient features.
It's definitely better than the google group we have now, even just for the search form.
(I'm not sure about upload moderation (think of what's on the google group), because I didn't upload anything myself.)
For fun, I decided to try an create something similar, and in the end I managed to make something.
You can find it here: vannilla.org/creamy/home.html
I've added three stories I've written in the past so you can read something.
The user interface sucks, yes.
Actually, most of it sucks, but as the thread title implies, it's an experiment and probably I'm going to tear down it all when I'm satisfied, but I'd appreciate it if you could check it out even just once.
