Starting this thread as a place to share online game network profile IDs/usernames, as well as discuss PC/Mac gaming in general. If a separate Mac thread is warranted, we can do that - the main reason I list Mac here is due to Steam's newly released Mac client.
Anyway, if you have a Steam username, one for Windows Live, etc, share it here to have it added to the Master List.
