Currently I am finishing off the 'Rules' section of the GUI. After this, I will need to do some final testing, probably with a public server or two and then it should be ready.
By "be ready" do you mean this week or in weeks to come?
Warning - while you were reading a new reply has been posted. You may wish to review your post. Similar, although I edited the Leader uniform slightly. The Team Editing GUI now opens the Avatar Menu, which means you can save, edit or load uniforms from your Avatar Favourites instead of messing around with menus and your own appearance to change it. You can also set team uniforms to blend with peoples' own avatars, so those with the alternate body set or different face colours can keep them, as if they'd actually put on a new uniform instead of being morphed into identical soldiers 
Just about to ask that. Sounds cool!
