For those interesting in trying out online gaming you can look at some websites that are geared towards finding games and players for online RPGs.
TheTangledWeb focuses entirely upon online games. Plenty of 4e, Pathfinder and PbP games always looking for more:http://www.thetangledweb.net
Pen and Paper Games is pretty cool for both face to face and online game finding.http://www.penandpapergames.com/
RPG Game Find is like the little brother to Pen and Paper games but I found the awesome Pathfinder game I play in there:http://www.rpggamefind.com/
You can look at the forums on RPtools for maptools games at:http://forums.rptools.net/viewforum.php ... 76f7e59c74
There are some other spots as well out there but for posting a game or joining one Id start with these... and yes sometimes even a Grognard friendly 1st edition game pops up.
Good luck finding a game all!
