Yes, I am. 100 per page. And of course, there are less than 500 posts on this thread currently so yours wouldn't show pages yet. But I know that when I've made a link before, with the hashtag thing by mistake, or possibly when I've followed others' links, the thread linked has come up as all on one page. But now I'm not sure if that was something that happened when the person making the link viewed AOOP. Because I've never had mine set to that, I don't know if it actually changed the URLs themselves (like it does when you click "show all messages") and now it's too late to ask anybody to check!
The Reality/Listen Up one in Relationships, that's linked a lot, and it always comes up as one page when I follow a link to it. But who knows what threads I've seen that on - I wouldn't be able to search it, I don't think, so I can't check the URL.
