The Mercurial mirror here on Bitbucket has received a pull request for the German translation. I went and told the guy that we don't use the mirror for development and that we don't even control it.
That added me as a reviewer on the pull request, which is fine. The pull request now shows up in my pull requests overview and I don't think I can remove it from there: I cannot decline the pull request since I don't control the
mirror/mercurial repository and I cannot remove myself as a reviewer.
I've remove myself as a watcher from the pull request, but that doesn't influence the overview.
