So to answer some of your comments:
We are using a private discord to post activities
We aren't gonna join every single groups discord to see there activity. Rather have it a simple form with an overview of there activities. When we require a more detailed view it will definitely be nice to have a place to look for more detail.
Every 3 months
Positing an overview of activities done in the month should be a relative low effort. This should not take that much more time then reviewing a single application (If tracking is done correctly). Next to that 3 months is a big iteration time to check changes made and overal activities. @DROT summed this up nicely in his post.
Missing groups/inactive groups
HLS is also considerd a special group which is not under GM but HQ.
Enternia and SAF are both considerd dead/inactive and are scheduled to be removed. In SAF case they can definitely still live on as a group but there in-game rewards are not required anymore as nobody actively uses it.
The point of these changes is so we, as group managers, have a beter feel of how a group is performance and can beter decide on changes they request. (Additional spawns, bases, etc).
