I have been testing out the admin addons with v3.3.5a and finding all sorts of problems.
TrinityAdmin was the one that worked the best so far so I have been using that and have started modifying it to work correctly with MaNGOS
As such, I have created a project where I have been updating the addon that you can download a working version for MaNGOS with 3.3.5a client.

So far I have fixed a few bugs and gotten the ticketing system working.
Although, the tickets are not displaying for one of my GMs but it seems he is getting different chat messages for tickets than I do which may be a MaNGOS problem.
Is someone from MaNGOS willing to commit alterations for me to make the addon work better??
