As my first question on the site was when the misspelled tag was found No features are active to use meta, edit, or chat.
In this case, should the tag be posted in Meta under "support" "tag" "re-tag"?
It is always worth checking whether the misspelled tag has only been used once (or very few times). If it has, then just edit or suggest an edit to change it.
Otherwise, I think that you should report it to the Meta of the site on which you noticed the incorrectly spelled tag.
Alternatively, if that site has an active chat room, dropping in there and mentioning it will often achieve the same result more quickly.
Per site meta - as you would a tag that needs to be removed.
The 5 reputation minimum for meta is not that high and I'd post the question anyway, (optionally using the mispelled tag) .
This is a bit of a cheat but you can then post a meta question about your question, even without the 5 reputation, referencing the fact that you had a mispelled tag suggested in the main question.
Its much better though, to post something worth an upvote before you meta it of course.
