Hmm.. i'll take a stab.
Suitable items:
Magmor announcements such as meetings, practices, and cancellations
News items of interest to scholars of medieval history
Local events medievally interesting, such as art exhibits or 'living history' performances
Items of clear and obvious interest to Magmor, such as armor/garb/A&S materials to sell/give away
Unsuitable items:
Funny cat pictures (unless medievally themed)
Random Youtube videos (likewise)
Most contemporary news items
Almost anything by Coldplay
Probably okay:
Mundane get-togethers with Magmor friends
Mundane items you nevertheless think belong in Magmor somehow
Whatever you sincerely believe might help us join as a community, explicitly medieval or not
Anyhow, those are my opinions. If you don't like them, i have others.
Relevant to not much, is anyone else getting weird emails from the Calontir Beads group on Yahoo? I think someone has a virus, but i'm unsure how to contact them.
