A question using the latex tag was recently posted, which received a number of down votes and comments which directed to post on tex.stackexchange.com.
MO predates tex.stackexchange.com and so at that earlier point the MO community set up a latex tag in order to have some place to get latex help. My question is there any way to post a relevant question under the latex tag now?
I don't see how this is possible given the tag info:

Please note that there is a Q&A-site dedicated to this subject http://tex.stackexchange.com [.] Most questions involving LaTeX are a better fit there, and if asked here, might still be migrated to the other site. Most of the existing questions with this tag predate the existence of the other site, they are not a good indicator for which questions now would remain on this site.
