Yeah, it is clear, but as Martin said, problem is somewhere else. There are columns name, firstname and surename, so yes, there can be more users with same firstname or surename, but there shouldn't be users with same name. Name is user friendly identifikator and as such it has to be unique. > > > >Karsten > > Oh, ok! I understand that now.

And it is bad. E-mail shouldn't be unique... ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc. Do you grep through log files for problems? Stop!
