I'm 100% for increasing the size of the weekly meetings, but do you think it would be prudent to do so at a slightly slower pace?
I don't know if Tim's friend who does Wiki-style website programming is participating this week, but if he/she is, then assuming you've spoken to Johnson and he's participating, then we're increasing Wednesday's meeting count by over 100%. For people are not a lot absolute wise, but a lot relatively speaking.
My concern is that the dynamics of the group can change so radically at a moments notice which could discourage members. I acknowledge that radical change could be for the best, but wonder f looking ahead it may make sense to let the group adjust
to a few new members through at least one weekly meeting before adding
new blood.
