What is an Item Request and how does it work?

If you can't find what you are looking for in a group, then you can post an 'Item Request'. The Item Request is a short description of the item you are looking for and is kept in the group you posted it in. This allows other users to be notified and review the request, if a user in the group has an item matching the item request then they can contact you directly or add it to the group.
