When I'm reviewing a tag wiki addition, it prompts me to
Approve, reject, or improve edits suggested by users
Most of the reviews I've done are in cases where there is no existing entry and someone decided to add it - great, I will accept if its fine. For short excerpts, there tends to be less problems with formatting.
However, recently I came across a review where the game does need an excerpt, but the suggested edit is just a run-on sentence. I'd prefer to edit and accept it (rather than having nothing at all) but that doesn't seem possible.
Approve or reject in such cases is straightforward, but how should I improve it? The prompt appears to be only applicable for users above 20k rep, which is quite far away.
