It's possible that I've mentioned this already, but if so I'm sure it won't hurt to bring it up again. This is a shameless plug for a game I enjoy.
For years I have been playing an text based online strategy game called Dominion. The community has become fairly tightly knit over the years, and long-time players are constantly trying to raise awareness of the game to recruit new players. It's actually pretty well designed for the experienced to coach the new, since players can join "packs" of up to 6 people where they play together, and in that way one or two knowledgeable players can easily join up with new players and guide them along until they understand what they are doing.
If you're the type of person who is interested in these games, you can get to the homepage from the link in the text, or at: kamikazegames.com
I'd suggest that any new players head to the messageboards, so they can get in touch with players that can help them learn the game.
