Other IM
because there are other IMs then just the core 3 and gamer related stuff
Such as Gtalk/jabber or myspace IM (even though I dont personally use myspace)
so having an other IM option just pretty much covers your own butt for the lesser known stuff
now for forums
ADD AN EDIT BUTTON
a search forums option would be nice so you would have something to point multiple variations of the same question to.
