Hello answrtek -
1. It sounds like you may be looking at the Saved Listings page without adjusting the Show Last ___ Days pull down menu in the upper right of the Saved Listings page to "All" to see listings that were saved past the default view of the last 30 days.
2. If you refer to the Notifications area, you can select them all on a page by using the check box on the right of the title bar and then clicking on the Delete Selected Events button or you can remove all notifications from your account using the Delete All Events button just beneath the filters.
3. I am not entirely sure what you refer to on your dashboard; I am unclear on what total count of 75 you refer to that refers to past events. If you refer to Account Messages, the most recent shows on page 1 of the events, but if you wish to Archive them you do need to select the checkboxes for them individually prior to clicking on Archive Selected.
If you refer to another area of the page, please let us know and we'll be happy to assist you further.
