Item 1 in the Plan in The Great Re-Tagging Call to Arms is
When you view a new question (especially if the question has only 1 tag), compare its tags to the question's content. If another tag applies, add it.
Regarding this item, I was going to point out how to edit question tags least obtrusively, “by hovering next to the tags list and clicking edit tags” but then found out that that option isn't appearing for me for ELL questions (1, 2, 3). (It does appear when hovering next to or over the tags list of an ELU question or another ELU question.)
I presume it isn't a reputation issue, since the ELL faq shows 200 points is adequate for the “Retag questions” privilege. Can this feature be added in ELL as well as in ELU? Or is it already here but for some reason not available to me?
