So what to do with all these Rares...?

[:1]Completely new to these forums, very impressed with the community here. I've been lurking for a couple of weeks...

So I just started playing D2 randomly (Torchlight wasn't cutting it and D3 isn't out yet) and I find I'm a pack rat. So any purpose to all these characters I have full of rares? I just keep stashing them away lol. Figured I'd do more killing if I stopped muling so much random stuff if there is no point to it all (and that will help a lot if I'm still playing after Sept 24 on the new ladder season)

I have no idea what any of them are, I see rare, doesn't help my sorc, mule it without another look... lol... *sigh* I a terrible packrat disease don't I? Prob caught it from smashing and digging around in all those rats' nests...

Thank you for you time,
