Our symbol on all exchanges is UNO, except Comkort calls it UN.

Install success with UN/UNO's Linux wallet has been tricky since the JacobUx team released their wallet update.  I don't run it on Linux and I'm not a dev, so I can't give a technical description of the problem, other than to say there has always been some magic involved to get it to run on various Linux distros. Success on Linux has been inconsistent at best, and the problem wasn't resolved with the last wallet update, unfortunately.

The last changes to the wallet are described here: https://bitcointalk.org/index.php?topic=527500.msg6375403#msg6375403
In the last release, UN/UNO was updated for heatbleed, checkpointed, and addnodes were updated.

I don't know exactly what Bryce has had time to finish, but I know he wanted to add some protection for Timewarp, resolve the Linux/Mac wallet issues, and some other things.
