I am really interested in yearly review, or something I suggested before to show historical activity of local board from the first day they got created, and it doesn't need to contain all the details, but only important stuff.
You mean like total amount of posts created/merits shared since creation? I am not sure how that would look like since some local boards were created in 2010 while some in 2014 so it wouldn't really be fair comparison. Or you had something else in mind?
A historical report from the beginning I won't say, because, as I said, the local boards appeared in different years, and therefore an analysis would not be realistic.
Now doing an annual analysis could be interesting, to get a simpler and more practical view of how things were developing in 2022.
