When I'm busy I don't have time to read the articles in detail - Ben and AS are often guilty of posting very interesting stuff I'd like to read in detail later - but if I "mark read" chances are I'll forget about it. So I add a browser bookmark which leads to a mess.

Would it be hard to add a "bookmarked" flag to a post? Say, with a green plasmadot alongside it and the forum it's in.

Somewhere between "new" and "marked read". Say "mark noted".

You'd have "Show new or marked only, show new only, show marked only, show all". Seems like this should be straightforward.
