HeadCount

HeadCount is a configurable World of Warcraft add-on that automatically tracks raid attendance, loot, and boss kills.

HeadCount answers the following questions:

How long is a player active in a raid?
How long is a player on standby for a raid?
How long is a player offline during a given raid?
What loot dropped during a raid and who received it?
What boss kills occurred during a given raid and who was there for the kill?
