Right, I first started reading webcomics when someone pointed out Megatokyo to me. That got me interested in webcomics, and I looked around for others, and PvP kept getting mentioned. So I started reading its archives, and I found I rather liked it. One day I decided to see what the forums were like. This was back when we were on the Image boards.
I didn't decide to start posting until I saw a forum game that caught my fancy, however. It was a simulated text adventure game, you know, the type where to "go east", "go up", "light torch", "search room", "kill grue" etc. Except this particular adventure thread didn't have an "operator" per se, rather it had each poster posting a new section of the adventure, however they liked.
Being an avid (some would say addicted) mudder, this was right down my alley. So I registered and wrote a lengthy post, including a section of mud-like combat of the player against an NPC. The NPC was described as being overweight, hiding in an attic, wearing a Han Shot First t-shirt which had pizza and coke dribbled over it, and quite surly. I named him Nerd.
The other posters in the thread, however, were offended that the new guy was apparently calling them all nerds, though they also noted that I included the mud combat section, which meant I was just as much a nerd. I guess they didn't know what to do with me.
And then I stayed.
