Getting rid of old posts on the “Updates” page is simple.
First, understand that the each of the posts on the Updates page is, itself, another page. You can see this if you click on the title of a post….it takes you to a different page where the post and all the threaded comments are. The ‘Updates’ page itself is sort of like an index page.
So to delete a specific post, just to to that Post’s page, and delete the page. It just takes two clicks.
1) Edit the post itself
2) Move that page to the trash. It deletes the post in the Updates page.
That’s it. Please delete all your old posts ASAP.
