I see a lot of moderators migrating questions from one site to another pretty often, but tonight I had a question which doesn't neatly fit into any in the list.
Is there a mechanism, or even a dedicated Stack Exchange site available to assist those with questions which don't seem to fit any of the site topics or involve nuances which cross the boundaries of multiple site topics to post those questions to the most appropriate site or possibly even trigger the consideration of a new Stack Exchange site to focus on a novel discipline or subject?
