Rename Existing Site

Is it possible to rename an existing WikiDot.com account ?

For Example:

I would like to change my site [http://movie-trailer-mania.wikidot.com] to another name.

I've spent quite a while looking through your documentation without success.

I'm sure I must have missed it, but by now I can barely see.

I must say, however: Wikidot.com is terrific !

easy to do, but extreme: Menu Site Manager - Extreme Action - Change base URL

I must say , however: Wikidot is wonderful!
