Well, your name links to your forum profile. But apart from that, maybe, for whatever strange reason, some people are only on the forum and don't play the main game? Or maybe they're only here for War Islands? I don't have a WI account, and I think that could also use a link, in case people want to show off how great they are at that game.
Then again, pretty soon we might get link cluttering, and I would advocate against that.
