It seemed in previous releases that players that left the guild were placed in the "guildless" guild and basically hidden from view. As of the latest release memberlist is now automatically deleting these users from the roster completely.
1. Is there any harm other than database bloat in keeping these users in the guildless area, hidden from view?
2. If there isn't , is it possible to add a switch to the memberlist addon to prevent the users from being deleted?
My current mod uses this information for historical purposes, and it would be much easier to keep the information rather than to try and parse both the members table and the memberlog looking for the user.
Another reason to potentially keep this information is for use in player tracking. In the beginning of this year we had a player borrow a whole bunch of gold from the guild, switch servers and change his toon's name. Using the pre-BC reputation values stored in Roster (they hardly change after a player hits 70, and act as a "player fingerprint") and the wowArmory, I was able to track the player down and make his life a little more difficult on his new server. (OK OK maybe I had a little too much free time on my hands )
