Install the extension CheckUser
(

What do you mean? You can ask the sysops to specify it in their
user page, and there is the page Special:Listadmins. An
administrator can configure his signature in talk pages to show
"USERNAME (sysop)", of course, but not in the history pages.

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.
