As for the repo, it can be deleted, but in general we don’t really delete things, we just hide them. As such very few people can mess with repos. Is the repo showing up somewhere other than github?
Searched the Dashboard for “performance publisher”, got Performance Publisher; decided that’s not the one he wanted, Then searched Jenkinsci GitHub for performance publisher and found the “go-performance-publisher-plugin”, which is the empty one, so only in Jenkinsci. Still not clear which one my Dev wants, but that’s my issue for next week.
