After pointing the umpteenth LaTeX question poster from StackOverflow to tex.stackexchange.com, I thought it would be nice if people got a suggestion when entering a particular tag. In this case, it could trigger on the tags
latex which would catch most, if not all, of the questions that would be better asked on tex.stackexchange.com.
It could show a message above or below the "Related Questions" box, offering a link to transfer the current form's contents to the other Stack Exchange site.
Sorry if this has been suggested before; if so, I couldn't find it.
