FindRole attempts to find players of a certain role for your group, and asks them to join you via a whisper.

It does exactly what players do, should they use /who to search for players to join their group. Only, it's much faster, doesn't forget names, and you don't have to madly push buttons or type things in. It will ask players once, and once only. And won't ask players that are already in your party or already in instances.

To use FindRole simply type /findrole (or /fr) to bring up the FindRole UI. The rest is self explanatory.

Also, type /findrole help for a list of FindRole slash commands not on the UI.
