so that I don't need scroll all the way down through the stream. Just a refugee trying to figure this place out. Thanks
click alerts on the top right of the msg board or click new posts in the menu pane in the middle of the top of the thread
If you've already been reading a thread, generally just by clicking the title, it will take you to the first unread comment. If you just want the most recent comment, there's a "Last Comment" column on the right, just click on the time shown(1 minute ago, 30 minutes ago, etc.)
While the above answers are good and correct, it's worth noting that this type of forum is structured in a fundamentally different way from OregonLive. This forum isn't a "stream of thoughts" but rather discussions organized into threads (a thread is a line of discussion around a topic). So rather than seeing the "most recent comments," you might be better off clicking on thread titles of topics that interest you most.
When there are new posts on a thread, there is a blue dot to the left of the thread title. Click that to go to the new posts Or, become a 24/7 forum lackey like SPD and read every post as it comes in.
The one I use sometimes, is the "go to first unread" which will do it too. It will be on the upper left below the "home, forums ..." banner after you click on the thread you want to read.
Up at the top of the board, do you see the Ripcity logo? Click the lowercase w about 10 times. If you have a weak computer, it may be more. A colorful menu opens up for the paying posters. If you need more help, PM me and have your credit card. This board has many perks and Easter eggs that were installed before all these newer mods came on board.
