Although I am not affiliated with the website, I'd like to mention
RPGRegistry.com. They've got a pretty big directory of gamers where
you can specify what games you know and how well you know them. When
I registered, I noticed that Hero Wars is in the list, so I'm pretty
excited about the possiblity of finding some more HW gamers in my
area.
My apologies for the only partially-relevant nature of this post.
