When we were looking to move from Yahoo to IO we decided to use ONLY subgroups for actual messages and conversations and us the main group only to hold the member accounts as required to have a subgroup.? Our reasoning was that in Yahoo we had? people in group A who were not in B,? in B and A but not C,? In C & B but not A, etc.? In other words there was no single group that had everyone.? So, when we set up IO, we created the MAIN group with settings that would not permit postings, adding files, adding images, etc.? In other words the only thing one could do was join or leave the group.? Then we use as subgroup for all the things we really need.? ?In our case, we are using all private groups (and subgroups) and only use Direct Add as the means for getting people into groups (no invites, no "request to join") so having to add manage the member in MAIN as well as the subgroups they need to be in was not a big deal for us.? I'm not sure how this idea would work open groups.
