@MichaelWehar the meta post is fine, appreciate it, it aids with publicity, but we dont need anyones permission to start, we both agree its a good idea, and its been done on another SE site with great success (
Physics), so lets not overthink it & Just Do Itâ„¢ ok? :) would like you to be the 1st guest, no one else. am ok with someone else but doubt they would be as well-known as you already are! & its not totally trivial to get 20rep on SE for chat permissions for new users etc...
