Vertex groups can not be named in blender 2.70 For some reason the name text field doesn't appear for vertex groups in blender 2.70. I tried in 2.69 and it's there and works fine. Was this feature removed in 2.70 or am I missing something?
Ctrl LMB  click, or double LMB  click on the name of the vertex group. That is now how to rename anything in that type of list.
