If you come across some content that isn't appropriate and which you think the moderators haven't seen yet then you can flag it for their attention.
Beneath the blog comment, discussion message or knowledge entry you will find a Flag button. Select this and you will be prompted to enter a short reason why you think it is not suitable. After selecting the Flag button on the form a task will be created for a group moderator to take a look at it.
If the item of content has already been flagged by someone else then you'll be told. If it has already been checked by a moderator who didn't think there was a problem then you will also be told.
