Days of the week aside, a live chat should be held as close as possible to the end of the calendar month so that people (like myself) with a limited download allocation can burn their spare change on something educational!

I don't know what other countries are like, but in Australia, ISP Broadband plans are usually capped and limit you to only a few GB per month. It's a monthly tradition to burn this on useless crap. I urge Phil in the strongest terms to put an end to this barbaric practice.

...and regarding this month, surely a live chat on February 29 is relevant to Astronomy!
