Greetings friends!
Finally got some free time to work through that to do list, two things added today:
Configurable time until teleport; you can now configure (with permissions) the time from after the request is accepted until the player has actually teleported. This one has been on the list for a while and I'm sorry it took so long.
Now supports the "CanTeleport" hook - just like NTeleportation. This basically means the plugin will now work with all your raid blocker type plugins, stopping the player from teleporting if they shouldn't be able to.
As usual please let me know if you have any other suggestions - /tpc and /tpb are both on the to-do list but will take a while to get done since I plan on adding them both to the GUI.
