phpBB forum has an option to provide list of new messages posted since last user visit.

It is really helpful, but it is not available on forum interface (or, at least, I cannot find it).

Can you make this option accessible?

You must be logged in and the top bar has a notifications which indicates the number of new entries - click on and select those of interest - Works for me!

This shows notifications on topics I am subscribed on.
I would like to see all messages since my last login.

Here is a direct link to that option: search.php?search_id=newposts

I guess, I could put it in my bookmarks...

Did you try "Quick links" at the top left then 'New posts'

Yes, that is it!
Hidden, but at least it is there.
