when we as designers finish a setup, and finalize the side splits, we post on the FSO forum, with a link. in this link, is everything every squadron needs, with exception of objectives.
when objectives are sent out, they are sent to each sides respective email list. not just squad co's, but everyone whose email is listed. after this email is sent to each side, we then post again in the FSO forum that each sides objectives have been posted, along with reminders of who is each sides CiC for that frame. i honestly don't see how all members of any single squad could manage to not get at least some of these emails.
