It's still in the works. As far as I know, tsuki/hirasawayui wants to either use wordpress or wait for Poniko's Basement .
Wordpress link here: http://uboachan.wordpress.com/
I think tsuki has contact information on it if you want to ask her directly about it.
Otherwise if it's being put in with the basement (which is going to be a huge amalgamation of YN related things), you'll have to wait a bit for it. I'm maybe a fifth of the way through coding it, and there's still quite a bit left to go!
Also we haven't taken applications for it yet either so idk.
