I kinda like how the online list is long, it helps to make forums and stuff nicer since you can get all the stuff on one page without having to keeping paging over for more posts. I dont really see the hard in long pages? Also, every second reload might be okay in a seperate chat section of the site, but would probably wreck havoc on the main page especially for people on dialup.
On a side note,
Great work NoPoles! The site is looking amazing.
