Reloading admin list

I was wondering if there was a command to reload the admin list after I make changes. I don't like having to restart the program after adding admins because it restarts the current map, which annoys the players on the server. If not, is there a way to restart the program without restarting the map?

As, so simple.

OK, that's odd. In my email, I received a notice that Manu replied to this post with with the "!readconfig" command, but that reply isn't in the thread... is that the right command?
