That's the archive board. The official (up to date) place to go for Hydrus is the official thread on

And yes, Hydrus is wonderful. I used to have a soft upper limit on the amount of hentai I could have on my computer because the more I added, the harder it became to organize things properly. Hydrus essentially removed that upper limit, and now I can have an essentially infinite collection (well, until I run out of disk space) while still be able to organize everything.
I wish that Hydrus-dev was open to contributions from others though. It would be able to be developed so much faster that way, especially since it's programmed in Python, but oh well.
