Hello May be these are very trivial question: - How can I find out, whether the same user has various accounts and give the false impression that many users contribute. I presume it must be via the IP (also in case of multi user machines that might be misleading). - How can I find out that someone is a administrator of a specific page? Right there exist a long list of administrators, but couldn't a administrator get a specific signature or something like this? Thanks Uwe Brauer.
