I was looking over a few other website forums and each post from different members would have their own little banner, like mine right now for example.
This adds a little personality between posts and it's quicker to identify who's posted when skimming through messages.
Also I'd recommend, if it's even possible in the first place, to reduce the risk of people using huge, irritating pictures the size limit could be 338x24, that's the size of mine.
What do people think? Too much?
