So I've been asked to start coordinate the third chat session, in which we'd attack the large (but slowly dwindling) number of unanswered questions on this site.
To facilitate the scheduling and finding one common denominating date, I've set up a doodle. Go to the following link and enter when you're available. I will then choose the date where the most people are available and post the date here as an answer.
The doodle: http://doodle.com/mibqkbyfmm79ez2u
EDIT: I've been pretty busy in the recent couple of days and haven't really had much time for this side project. I've therefore expanded the scope of the doodle to incorporate more of this month. Hopefully we'll find a good date (please update your choices) for everyone!
