Now wheres the fun in me leaving you guys alone ;P
I have a question before I reply, as I'm not sure how a certain watcher power works rulewise (it's the first time I play a mage).
A watcher can be used as courier (SR4a p189) to send a message to a person known to the summoner. So if I summon a new watcher (which I should be able to do on the astral), ask it to go to LJ, how long will that take? If it goes really fast, I'll summon a new watcher, have it go to LJ and I simply follow the spirit to find my body back. Otherwise I have to think up plan B.
