I have 400 namecoin.. That's it.. It still looks like they have namecoin support from my account. Maybe that's only because I have namecoin there..
I had high hopes for them too, but I must admit, whenever I want to actually trade BTC, I headed over to MTGox... I kept a balance there for a while, but I never actually felt like trading where the volume always sucked.. Campbx always felt that way too.. I haven't been there in a while either.. I hope for their sake that they're doing better than Ruxum.
Bitcoinmarket has practically zero volume these days... Last trade there was on 11/06/11. That one makes me really sad. Wasn't that the very first exchange? They held my Bitcoins for me that I purchased at 1.39 cents until after their peak of $30.
