A suggestion

I feel this site would benfit from a button at the top of the screen called "jump to first unread post" somewhere around the "post reply" "bookmark it" "watch topic" buttons. Ive been on other forums where you could click a button and the newest post would automatically be brought to the first one that you'd be reading. I know this site could do this since it knows what post are new based on the "light bulb concept." It would save time not having to scroll through post (and) trying to remeber where you last left off.

I don't know about other people's computers, but my iPad displays a "recent topics" button which does exactly what you are asking to do.

My fault for being vague. Let me explain better. When you click into a thread that you have read before (and has new posts as indicated by the yellow light bulbs) you have to scroll through post you have already read to get to the new ones. Some times this is only a couple post from the top, sometimes you have to scroll down through many previously read replies. If you could jump to the new post on a thread it would save a lot of time.

THIS!

When I visit this site, I go straight to the 'Recent topics' page. It lists the most recent threads with activity. On the very right is a column with a link to the most recent post, but that isn't what I want, I want to go to the oldest unread post in that thread so I can continue reading the conversation from where I left off.

I also always open them in a new tab. Whoever invented the back button on browsers (so long ago) did us all a big disservice as it turns the world wide web into a world wide string.

I'm not too lazy but I like the idea of the page opening to the thread section I have not read If I can't get that, a go to last post or bottom of page would be good.
And Paul since you need to feed the machine, how about an app for my Samsung phone that makes the back button not so touchy, "mine is on the bottom right corner" subject to bad holding or fast scrolling movements losing your page.
