We already have several questions on how to cite something from MSE, see the questions linked to this one. Would these questions deserve to have their own tag at meta?

Probably new questions about this will be linked to that one, too. So it should be easy to find them even without a tag....

I've created cross-posting, since there was a new question at meta. (Perhaps more will come in the future.) I've copied the tag-wiki from meta.SO; if you think that something specific to our site should be added, feel free to edit it.
