+== User administration ==
+
+There are two kind of accounts: normal user accounts ({{{<name><number>}}}, e.g. {{{mustermann1}}} and admin accounts ({{{<initial><name>}}}, e.g. {{{gmustermann}}}).
+
+Please use the user accounts preferably to do the benchmarking etc. work which do not require privileges. Use the admin accounts only if your privilege doesn't suffice to do the required work. Please be careful, we trust you know what you're doing.
