Main function:
This is a mini addon that auto-replies to whispers asking where you are.

It has a small list of favorite location where it will give detailed information for, like the Orgrimmar Mailbox, Orgrimmar Auction House and such. It can even tell the difference between being inside or on the Orgrimmar Bank.

The addon currently has no known favorite locations for Alliance cities, but I don't feel like spending a lot of time on them.

Ace2-based.

Additional features:
You can also manually activate the location whisper by whispering "!location" to another player.

Commands available:
/whereareyou [version | enable | disable]

Example:
[Zerotorescue] whispers: where r u?
To [Zerotorescue]: I am at the Orgrimmar mailbox (50,71).
----
To [Zerotorescue]: !location
To [Zerotorescue]: I am inside the Orgrimmar bank (49,69).
