I can't see any posted / new deals!?
Chances are you're looking at the latest activity, which isn't the same as the most recent posting. To see the latest and greatest, simply click 'sort', then choose 'Recent Posts'. You may have to scroll past the announcements first to see this menu.
For desktop users, there won't be a 'sort' option, but instead you can click on 'New Activity' to open the dropdown, and from there select 'Recent Posts'!
