/cl_guidServerUniq 1

Everyone who wants to keep his guid in safe on should type to the console: /cl_guidServerUniq 1

It's a basic condition for admins before they gain an admin level, but also if you already have an admin level, check it out.

It's set by default on 1.2, but not on 1.1!

This command will build a new guid, so ask a higher admin to update your admin level if you had some before.
