Thanks for picking this up, @sklin93! The discussion and issue have been up for a while now and there haven't been many active contributors in the past few months, so let's go with whenever is most convenient for you. Which timeline do you prefer?

The first weekend of January (Jan 7-8) would be better! Thank you @codesue!
