Would it be possible to add a feature that would allow for one-time only teleports on joins for specific players?

Reason for this is that on heavily modded servers sometimes the server crashes when a player is in a chunk with a problem. Deleting the player.dat file solves that problem, but also removes everything the player has in his or her inventory.

So the idea is that all the players come and go as they would on a regular minecraft server without plugins, each player joins on the last location he was in. This can be made configurable so people can decide to use one-time only teleports along side with the original function of this plugin.

Then if a player is affected by a chunk problem you could do something like:
/tpLogin <playername> <X Y Z>
And then the next time that player joins he's teleported to X Y Z instead of his last location or the default location set for the tpLogin plugin.

I forgot to mention the following in the ticket. You can probably teleport offline players several ways. One way would be to edit the coordinates inside a player.dat file. There's an inactive plugin that had this function called VanillaExtract: http://dev.bukkit.org/bukkit-plugins/vanillaextract/

That plugin's author has made a class to allow for methods for editing almost every detail of an offline player. http://forums.bukkit.org/threads/lib-tut-improved-offline-player-nbt-editing-made-easy.92627/

Thank you for reading all of this and for your consideration.
