Delete LiveJournal Memories

This FAQ page from LiveJournal helped me clean up my LiveJournal. This bit of information helped me the most:

Editing or Deleting Memories

You can edit an existing memory by attempting to re-add it (using one of the methods above), or by finding the entry in your Memorable Entries page and clicking on the [edit] link next to the memory's description.

On this page, you can edit the memory's description, keywords, and security level. You can also delete the memory. This does not delete the original entry; it only removes it from your memory listing. There are several ways to delete a memory:

• Deleting a Single Memory: Erase your description, then click the submit button. If the entry has been deleted, you will see a button which will allow you to delete the memory.
• Deleting Multiple Memories: Click on the specific memory category that contains the memories you want to delete, and add &multidelete=1 to the end of that URL in your web browser's address bar. Check the box next to each memory you wish to delete, then click the Delete Selected button.
