I've been around the original trilogy for a while now and have a pretty solid understanding on what belongs on what sites. As of now, though, I only have vote-to-close priviliges on SF.
I'd like to help out SO and SU with migration when I see questions that are clearly meant for another site. Is it acceptable to flag a question for mod attention so they can mod-hammer it over to the appropriate site? Or is it better to just let the community sort it out.
One thing to keep in mind, and a big reason I'm asking this, is that there are times when a question will sit on the original site for quite a while before it eventually gets migrated. If I see that happening I'd like to flag that, but I want to make sure that's not an abuse of the flag system.
Or maybe this is a community-specific thing that belongs on the individual site metas?
(sorry if this is a dupe, didn't see this particular issue addressed in other questions)
