The Dashboard is a splendid tool for monitoring the progress of a group. However, the Activity tab completely breaks when the education program it monitors is successful, that is when one of its participants becomes a Wikipedian. I just stubled upon such an example. One of the students in one of my programs became a Wikipedian - and started adding dozens of redirects, adding {{italic title}} templates to articles on biological taxons and so on. While this is splendid and fills my heart with joy, it also breaks the Activity tab completely, as it's now filled with his edits only. Would it be possible to (temporarily?) hide him from the Activity tab? This would also be useful for courses where the list of users includes both hardened Wikimedians who do plenty of work unrelated to the project and new editors.
