This works good for account names where u don't want your users to create ugly account names. 3 rules apllied in it:
1. an account name must start with Letter or Number
2. the only valid signs are : ^%&'+-@. and (space (chr32))
3. a sign can't be repeated by any sign execept space which can't be repeated as well. |

Comment:
It took a day for me to get to that..(well i discovered regex only 2 days ago) it wasn't easy but it works exactly as intentioned, for some reason negating a repeated char seem to be hard task to program with regex, and that's why I hope you find that expression useful.
