Inside OnPluginStart you should only check to see if the client is connected, and not in game, as there could be some overlap where a late loaded plugin could miss a few clients if they're still loading in. Also, no need for the IsFakeClient check there as it's checked again inside of OnClientConnected. Other than that, the plugin looks great. You should also make a note that to compile they'll need your "mckayupdater" plugin (although that should be obvious to anyone who knows what they're doing).
