Thanks LM. That's handy.
I was referring to jumping within a thread though. vB has a link at the top of every thread that lets you jump to the first unread post within a thread. Even BT has bold text and 'red balls' at WmW that let you know where you left off last time. In long involved threads, like when RC talks to himself, it would help to know where we last left off. It doesn't necessarily have to be a link like vB, but even a visual reference would help.
