Since I didn't want to start making a topic for each webcomic (though it would give me more posts xD) I'll make a short list here
Better Days (http://www.jaynaylor.com) [Yes, I have all the work he's done in his catalog, torrent FTW]
Goblins-life through their eyes (http://www.goblinscomic.com)
CAD (http://www.ctrlaltdel-online.com) [this one is my favourite, updates quite often]
Please, I'd be glad if you add any other webcomic I don't know about.
