Don't know. If the British have more alternatives for the word set for things the Americans use that word for, then it's probably a good idea to use them.

Originally posted by rheymans Very good. You are quite a problem solver. If anyone is interested in Mephisto's logic, PM me, and I'll give you the answer.
No, you are mistaken.
