I received the following, I think due to the action of James promoting me to sysop on MediaWiki:

It's very misleading to receive this as a watchlist notification. Also, there is a separate Echo user rights notification, so maybe this should be blocked by an Echo hook (but it's confusing in its own right for a standalone install).
