Though I don't think that's the answer that you want.
The problem really is that the logical navigation model that we're using doesn't allow for more than one thing to be paginated on any page, and we're already paginating the list of comments on an event.
What I need to do is provide a link to a new page that lists event attendees and then paginate that. But failing that, only the first 25 are shown on the "who is attending" popup on an already paginated event page.
All improvements will be made after I finish re-writing the entire UI to work in Go.
