I'm in the process of updating TenUI Widescreen edition with the help of some "Old Timers" like Alza (Who takes care of the oUF layout).
Some abandoned addons have been updated, as well was some repairs to others to keep the original package as complete as possible.
Some addons have been exchanged (mumble was beyond current repairs, so I exchanged it for Prat for now) and some other additions/removes are done in the package to shift around functionality.
I hope to have a initial release ready somewhere next week and that this release will be as close as the original UI was made.
I know Tenelov also keeps an eye on the releases, as he's still active here and on the russian forums, but doesn't play the game anymore.
