As someone who doesn't really use the IRC, the only time I get a hold of a GM is in game when I meet up with one. I know I could use the forums, but I personally have never had a problem so bad I needed to contact one on the forums. I like the idea of a command that shows all GM's/Admins/whoever who are online. As said above, I think it's more of a convenience rather than a stalking tool, because a surprising amount of players don't even use the forums (I being one up until recently).
