Any space in an ArM game?


I'm looking for an Ars Magica forum game with an open spot. I regret I don't own the ArM5 sourcebooks, but I do have ArM4 and I'd be willing to work off that if you can forgive me when I'm outdated and help me with anything ArM5 I get wrong.

I have an ArM4 just-gauntletted Tremere mage (non-combatant, slight focus in Im/Re/Au/Aq) that I never got to use in an old abortive campaign if that can be converted; otherwise, I'll happily chargen whatever your game needs more of.
