Okay, with the new forum look, I thought I'd do another TIP post, this one explaining some of the icons that are new, and some of the quick links to be found.
First, the user icons. Next to each post you'll see the user's avatar and username. Underneath, there are some icons. See attachment for screenshot.
Next, at the top of every page in the forum, you should see your User Info panel. There are some links to the right. You should see "
Show unread posts since last visit." and "
Show new replies to your posts." You can use those to see the most recent posts that were made either to you or to the forum since you last viewed. This way you won't ever miss a post!
And finally, either by using the above described links, OR by browsing the forum from the main forum page, you should see a small icon on the far right hand side that looks like this:

... If you click on that icon, you will be taken to the most recent post made in any given thread that you have not read yet. So you no longer lose your place in a long post!
Hope that was helpful!
