On the activity feed for a wiki I admin, two activities have been marked with a red exclamation point and say: "This edit has not yet been patrolled". The two edits are perfectly fine; nice messages from a registered user, nothing spammy or unusual or out-of-the-norm. What does this alert mean? I tried to google, but I couldn't find anything that would explain this and I've not come across it before.
