I decided this question was off topic, so I voted to close. The problem is that I closed it as off topic and I thought it would be better suited on English Language & Usage.
However, I couldn't choose that (English Language & Usage) in the pop-up.
I think there should be a "more" link in the bottom of the pop-up when someone wants to close a question as off-topic so it could be migrated to a site not already listed. If a site in the "more" section would already have a vote to get the question migrated to there, it would be listed without the need to click "more".
Is there a reason this is not yet implemented?
