The new patch
 

Total newb here, how do we use are mods after the patch?
Wait for the authors to issue a new version? How do we know that a new version is ment to be post patch?
I dont plan to do any toc stuff.
Finally please, please, please answer, I cant use just one toolbar, thats some sort of torture that Blizzard are getting a kick out of :-)

Get to your character log-in screen (where you pick which char you want to play). On the bottom left hand corner of that screen is an "AddOns" button. Click it. At the very top of the window that opens, is a "Version Compatibility" check box. Turn it off. That will let you run with your existing mods until the author(s) release their updates.

Most authors say which patch their mods is compliant with.
