AniDB

it would be nice to be able to request for title editing, so we can remplace any generic Episode XX, unknow, unk and other -

You can do that already

On the anime's page, click on the ep-number in front of the title you want to change. In the next window, select "Request edit", change what's wrong/missing and click "Request edit"

Btw, another way for changing ep-titles is the "!seteptitle"-command in #anidb@irc.mircx.com.

oups!
