I was recently introduced to another webcomic, Order Of The Stick. http://www.giantitp.com/comics/oots0557.html
I read some, laughed my butt off, so went back and started at the beginning. I wasted my entire weekend catching up.
If you are, or ever have been a role playing gamer, you will get a lot of the jokes. If you haven’t played RPGs, then a lot of it will just not make any sense at all.
On that note, I was just invited to be a guest at my very first Con. That’s actually really cool.
