Ellou!
I saw, that some of you can't find new releases, because for example they don't have site or irc-channel (like Cat Chan Scans).
Have you looked at #lurk? They bots have great number of new and old releases (bots are with %). If you list one of them you'll get website adress. In 'search'-pool you just need to type manga title, that you like and will get list of bots + packs numbers (for now bots with yaoi and yuri aren't working, but hentai does -> hentai, yaoi, yuri have other site than rest).
That's all
Have fun!

PS Sorry for bad grammar and spelling...
