Cannot log in
 

I am using several user names at my forum -- in its very early stages -- so that not every forum starts with a post by the same person. Right now I cannot log in at all -- not under my administrative name, and not under any of my ordinary user names.

All I get is the message that I have used up my login attempt quota and that I have to wait 15 minutes before trying again.

What's wrong? how can I correct it?
