So, I'm relatively new to stackexchange and mainly participate in R-related posts to SO and statistics questions on CrossValidated. I've noticed that when trying to flag a question as off-topic, if the post is on CrossValidated but should be on SO, there's an option to flag it as such but the reverse isn't true. Thus when someone posts a question to SO that is really about statistics and no so much about R, I'm not sure how to flag it.
I've read about the limitations to the flag interface here: More options when flagging for migration and here: off-topic site list?. I realize a lot of what is posted on SO is not statistics-related, but it seems like it would be helpful to have the flagging interface be tag-dependent, maybe? So, questions tagged R (or another statistical language) in SO would be able to be easily flagged as relevant to CrossValidated.
Or, maybe I'm missing something obvious about how to suggest a question be moved from SO to CrossValidated.
