BGinvite automatically handles raid invites for any Battleground( i.e. Warsong Gulch,Arathi Basin and Alterac Valley ) - No more 'invite plz!!!'.

Typing /bginvite will bring up the interface. You can bind sending invites to a key or use the interface.

As the party forms the raid will be created automatically and additional invites will continue going out if you have AutoInvite enabled. BGInvite will manage the RAID going forward inviting as needed and will remove anybody not still in the battleground (if you have Purges enabled).

Players that deny your invite are blacklisted and must be manually removed using the Blacklist Tab prior to continued invites. Players that are already in a group are sent retry invites every N seconds up to M times (depending on how you configure).

Configuration options:
AutoInvite - automatically send out invites
AutoPurge - automatically purge players who leave BG
Whisper - whisper a player to leave their group

Magic word - any word or phrase you want that triggers an invite to a player when they say or whisper it.

Invite Timeout - how long to wait between sending out invites if autoinvite is enabled.
Purge Timeout - how long to wait between purges if autopurge is enabled.
Retry Timeout - how long to wait between retrying an invite to a player who is flagged as Already in a group.
Max Retries - number of times to try sending an invite to a player who is flagged as already in a group.

An interesting side-effect. Even if you did not start a raid/party and you are promoted to an officer/leader BGInvite will still handle invites for the raid. So if you get in a tad late and don't start the invites, request to be promoted to help the leader get invites completed.
