I'm here for the same reason most are, to learn mapping. I've been playing D&D for several years now and I'm always the one to make maps (granted, they're on paper and not as stunning as the maps I'm finding here, but they're better than anyone else my the group can manage). A few weeks ago one of my friends (not a registered user here, I don't think) directed me to this site and told me I would enjoy it, so I told him I'd take a look when I had time.
I had time last night. I was amazed.

I look forward to joining this community.
