Today someone created the tag [recurrence-relation], which seems to me to cover the same ground as the already-existing tag [recursive]. I'm tempted to replace [recurrence-relation] with [recursive] in that question, which would cause the former to disappear as a tag.
However, I think [recurrence-relation] is a better tag than [recursive] for questions on this topic. I've never liked [recursive] as a tag, actually. I think my problem with it is aesthetic: Our tags tend to be nouns, and this is one of the few (the only?) that is an adjective. So I'm also tempted to request that [recursive] be merged into [recurrence-relation].
Since I have two different thoughts on this, I thought I would see if anybody in the community has strong feelings one way or the other.
(For the record, the question is Common Term for Differential Equations and Recurrence Relations.)
