Yes... But it could be potentially buggy
IE: It's 1 away from the max, and 2 people join at the same time
It catches the first player and redirects him, but before the command gets to him and disconnects him, the playercount is still risen when the 2nd one gets in the server, so the player count is and always will be when someone connects rd_maxplayers+1, rendering the plugin useless until someone else connects
