http://unobtanium.ioblazr is already* working on a newer version and the site should be out of beta by this weekend.
If you are interested in contributing time/services/etc join #unobtanium on freenode.

Doges, the new site looks fantastic!! However, the decimal place is in the wrong position in the UNO/BTC price:
1 UNO = 0.1 BTC 1 UNO = 10.0 BTC (January 2015).
