MUC Logs

I am using a customize Pandion with the ability to create rooms disabled. I am looking at enabling this option for my users but I have a few concerns.

  1. Muc Logging seems to be erased when a room is desroyed. Is there any way to have logs always kept in the database?

  2. Is there anyway to keep rooms more organized? We have about 900 users and that could mean pages and pages of rooms listed.(IE a seperate section for user created rooms?

  3. Is there a way to have rooms expire when not used. As will 1) they would be expired but logs still kept.

  4. Are Muc logs also stored in xml files or are they just in the database.
