In the forum listing of threads, you can select which page of a thread to jump to. Inside the thread, you can scroll down to the bottom of the page and select which page of that thread to jump to.
I sometimes find myself wishing that the selection of pages was also at the top of each page of multi-page threads.
I cannot always tell what a response is in reference to if a quote is not included. If the name of the writer of the comment being responded to is included, I may want to scroll up to find that writer's name and read the comment being responded to. If it's on the same page I'm currently reading, that's great. If it's on a previous page, now I've got to scroll all the way back down to the bottom just so I can jump to the previous page.
I agree with that. I'd also like to see the thread title repeated above the reply box. Many times I have to scroll back up to the top (used to be back to page 1) to see if the MSC or client was named in the topic so I don't inadvertently violate rules.
