This addon monitors the activity of players above a certain rank in your guild (to filter out counting lower ranks such as alts) at certain points defined by the user. If you are a raiding guild this marker may be set at the start of invites for a raid or when the raid begins. The results can then be filtered to show the people with the least and most activity (by default the addon only shows online people in filters but by clicking "show offline" in the GUI menu you can toggle this option).
The addon can be run using commands and/or the GUI
/oc menu (Opens the GUI)
/oc rank help (displays some help on filtering the ranks including the number associated with each rank)
/oc rank set <value> (sets the minimum rank to be checked by the addon when counting attendance e.g. /oc rank set 4 )
/oc check (checks who is online and stores it locally, you can only do this once per login and you will get a confirmation message to ensure you are doing it when you want to)
/oc recheck (Rechecks who is online)
/oc show all (shows all the stored characters (only online?) above the rank defined above)
/oc show above <value> (shows all the stored characters (only online?) above the rank defined above with an attendance HIGHER than <value> )
/oc show below <value> (shows all the stored characters (only online?) above the rank defined above with an attendance LOWER than <value> )
/oc reset (deletes all the data collected by this addon regarding attendance, there is no confirmation at the moment, use at your own risk)
/oc undo (will undo the last check if possible)
The current version is stable. If you have any bug reports, comments or suggestions i would be happy to read them.
