This user seems to be really keen on editing the excerpts for tags. Don't get me wrong - I really have nothing against people trying to help but as a reviewer I am not sure if they are all that helpful in the end and sometimes I am not sure what actions to take so I'd like to learn and improve my judgement skills a bit.
I know I can skip if unsure, but since I am already able to review the suggested excerpts I'd like to contribute and do well so I want to learn what a good excerpt is.
What I am specifically referring to is number 3 and 4.
The excerpts are quite helpful because they generally describe what the tag means but are also too minor as none of the suggestions mention when and/or where to use the tags.
note: you can view some of the excerpts clicking the tag wiki link in the users profile
When I reject a suggested except text as not helpful the reason does specifically say
This edit does not follow any of our tag wiki guidelines and is unlikely to help instruct future visitors in the appropriate use of the tag
which makes me think that it's a big part of the suggested edit to actually instruct where it's appropriate to use the tag and not only suggest the meaning of the word on the tag.
What are correct actions to take against those excerpts?
