Memories

Memories are bookmarks to entries around the LiveJournal site that each account can have.

You can memorify an entry in any journal.

These are like tags in the respect that you can categorize entries, but the list of tags stays with the account that owns the content. Memories are owned by the account and tags are owned by the journal.
