"Bookmarking" as in "back in the day" kind of bookmarking.

I’m looking for a way for a user to bookmark his place when reading a blog. Searching the plugin repository has been frustrating as I get plugins for bookmarking the site in a browser or for sharing on social media.

Say there are 100 blog posts. The reader gets to post 34 and can then bookmark it. Upon returning to the blog and logging in (I figure this would have to be tied to a login to work) he can then go straight to post 34 again.

Any such thing exist?

Thanks – Skippy
