1. If you are flagged for name change.
Enter your new name but do not press enter.
Crash wow, Alt f4 or something and when you restart wow you got the old name back and the name change flag is gone Worked for me on Eu for a few days ago.
2. Fly without mount.
Mont up on a vendor mount (i use traveler´s Tundra Mammoth) Klick the Flight nps and at same time talk to one of the vendors.
Sell somejunk and fast as possible klick on the flight npc´s map vere you want to go. And woila you fly with out mount!
(The fly speed is slow as the mammuth walking so dont take a long distance flight as i did the first time. (from sw to if) damn i was flying for more than 30 min
