I've noticed that you cannot choose a specific page in a thread. You can only go to the first or last page, or move from one to the other. The roleplay I was in, Myriad Reality, had over 6000 pages and gained them quickly. I would always read the posts that had been made while I was not there before posting myself. For that to work, I had to choose a specific page. I understand that this is a work in progress, so it may be on the to-do list, so I'm just checking.
