@Jan and
@gitagal - I thought I'd mention it in case you guys would prefer to not "page". There is a configurable item in your profile (the little person icon on the top left corner of the screen). It is under "Change your Site Preferences" and is called "Show how many items per page?" - it is next to last from the bottom of the list. If you set it to a pretty high number, you won't have "pages". I set mine to 500 and so far, most threads I've been following have had less than 500 posts, so I just scroll all posts from a single "page". This is a personal preference for people - some like to see less posts on a single page and like "paging", some would rather have lots of posts on a single page (making extensive use of the scroll bar) and not have to "page". The "paging" concept works well for people with slow internet speeds and/or primarily using their smart phone. I almost always access ATP from my home computer, have pretty decent internet speed, and don't really like lots of "paging" to see all posts in a thread. Dave made this a configurable item to satisfy the different preferences.
