Installed Gnome but I don't want gnome 3

view story

http://askubuntu.com – I installed gnome because I liked the old gnome, but I installed Gnome 3, and even when I go into gnome classic, I can't right click the top and bottom bars and customize them like I used to do in Ver 11 (or 10... I'm not exactly sure... but it wasn't 12) of Ubuntu. Anyway to revert back? I'm in 12.04 (HowTos)
