For any members who haven't written any messages within 3 (?) months, move them from Member to Lapsed Member, which removes their read/write privilges on all but the #ground-rules channel. To get reinstated they just have to do a simple action--ping the admin email group, or maybe ping the bot, and they'll be reinstated.
Perhaps just before you are switched to be a lapsed member, the bot @mentions you in a main channel, so that others who are participating can see you're about to become a lapsed member and maybe ping you to encourage you to particiapate?
