Google Sites

Arghh...
In trying to create several Google sites as an assignment for another class, I have found several things that I would change, lets just call it constructive criticism.

#1 - Give options for site name if that URL is already taken (I remember either AOL or Yahoo will offer suggestions for usernames if your idea has already been used)
#2 - Tell someone they have been successful in creating a page! The only notification I got was "Creating Site" but it never did anything. However, when I logged back on to Google Sites, it said I had 3 of the same site b/c I kept trying over and over.
#3 Explain why I can't create more sites at this time. Is there a limit? Is there something wrong with the server? Does it realize I'm an idiot?

Well, good night everyone! :)
