It's been stalled for a while, partly because a month after this post I got busy with university away from London so wasn't around to take the lead on this. (I was never planning to move in on a permanent basis for a while due to university, but was/am interested in the times I'm not away e.g. the summer, and would like this to succeed even if I don't directly benefit in the short-term.) I'll be back in London in time for this Sunday's meetup, so I might mention it then, even if only to see why it didn't happen. But if it goes ahead in future, it will probably be better if someone permanently in London (and maybe looking to move in sooner and permanently) took the lead on coordinating interested parties to meetup, discuss expectations, and do viewings. But I still might be able to help from the side.
