COOL! Unread/read markers will be useful when there's more topics. For now, I can kinda tell at a glance, but when they get more full and more topics pop up, you need them.
IM Infos good too, because the profile info looked way too empty before. At least I thought so.
I also fixed the paging now so that multiple-page threads have links to the pages shown on the forum index, when you've posted you will be sent straight to your post where it's been added, and a small button next to the titles of unread threads allows you to skip straight to the first unread post.
