George wasn't at the meeting, since he was in France trying to sneak into Beauxbatons to check on Gabrielle Delacour, but he'd have had Fred sign them up for Recruitment and for helping with the muggleborn hotline and helping get muggleborns to safe houses.
(Which I think is probalby the thing you forgot and were going to add in? :) )
Fred also would have noted that they're working on a new protection line for the Order, that it's almost at testing phase, and that they need some volunteers.
