In lieu of an active GM, how about we set up something in the interim?  We could have a Disembodied Voice that guides our characters.  Said voice could even probably be all-knowing, controlling various aspects of our world.  

The best part is that the Disembodied Voice can be controlled by anyone to push along their character's story or create plot points.  And if/when the GM comes back, he can decide what to do with the Disembodied Voice (DV for short?).

TL;DR - The Disembodied Voice acts like a questbook.

[@Zanavy] The Disembodied Voice(DV) can probably guide Jill to create her online business.  

DV's also going to be ruthless and set our characters up with an apartment that has noisy upstairs neighbours.  The question remains as to whether it would be war or peace.
