(If anyone can invite me to be a member of /graphic-notation so that I can post I would appreciated it. Although I am somehow a moderator of that channel, the channel admin option does not allow me to invite myself to be a member. 😆 @mic? - I can do all sorts of dangerous things to the channel accept post to it :) )
