Test is updated on EQInterface.com. I'll fix all the button changes I didn't do when they first introduced new button templates a few years ago when i get to it.
Basically the UI is ready to use but I can't test it 100% until I go f2p in March (different setups for f2p players (no shared bank, money etc - all need placeholders rather than blank space ). I am around in sw.bards because someone bought me a 30 day card to make sure it worked.
Expect an upload on March 16 - probably close to servers up time and expect several updates as the day/week goes.
