If I try to create a user with the username, say, John.flux then it complains that the "." is not a valid character.

If I create the user on the command line (with adduser), it works. I have now been using the username "john.flux" for the last year in Ubuntu with no sideeffects or problems at all. It appears to be entirely safe to do so.

The reason that I need to have this username is for the revision control system that the company uses. My windows username is "John.Flux" and so my linux username needs to be the same. The revision control system uses the username for commits etc.
