I don't know how to do Data Explorer queries, but my perception is the Earth Science Stack Exchange site was much more active around 2015, and I want to help the site with more geology questions and more geologists answering.
The problem is I might fill the forum with geology questions, while geology is only one of the branches of Earth Sciences.
I am not receiving answers, so could I make the decision unilaterally? Or can other users of Stack Exchange discuss it?
Could I use the logo of the site in the ad?
