Keeping tabs of what the admins do...

The built in edit log planned for a later release should cover that, but yeah if you need it public I guess you'll have to store it somewhere. Ideally somewhere outside of CB Activity. A custom database table with a Joomla reporting extension to output data from that table might be more ideal. I'm suggesting this because the more unnecessary data to CB Activity that is in CB Activity will slow it down more and more.

Yep that would be better, it overreaches my programming ability though (I am good with CB and with Joomla but am otherwise very limited... Hell, I even have to read up on how to write HTML now).
What I think I will do is simply let it run like this as I doubt that we will even see 1% of activity being produced due to the above AA.
With the addition of the EDIT banner that the edits are tracked, this 1% should drop even lower.
Regarding overload, yeah I had it already last year when notifications swelled up to nearly 4 GB on my International Friends site. Started radically pruning old ones and now it is going ok. Will likely do the same with the Activity if I ever get to it(although I will transfer them to a long term storage drive instead of pruning them). I have about 500 x more notifications than activity on my international Friends site (although its been dead since the pandemic started).
