Well, the peak of my enjoyment was when I started working on RIFT comic.
I had a nice thread where all people from Toribash (even guys from staff) were coming to discuss in which way the comic will go, and what else I will add to story, and everyone wanted to be in it, part of it.
Posting new pages and having discussion with people was true happiness. :]

Than forum database was deleted and forum reverted. People lost interest, many left TB, I started to slack... Death. :[
