Well, the only one I found which lets normal players teleport themselves is
this (for TF2, it says)... ;)
Here's some plugin for an admin to bring a player to him or to teleport to a player (goto/bring), and
here's some plugin for an admin to save a location and then teleport players to it...
OnMapStart is there because of
this, but I honestly don't know if I really needed to have it there, haha... It gets me confused... Well.
The default case on the MenuHandler got there because I thought the plugin didn't compile when it wasn't there. When I removed it now, it compiled anyway. Duuuuuh... Well, it's the truth ;)
