Just a thought I had. On at least two other forums I visit if a thread is multi-paged they put links to each page next to the thread topic.
For example, a thread called, "Thread Topic," that has four pages.
Thread Topic (1 2 3 4)
Each number is a clickable link.
If we had that here, I think it would be a boon.
Kick it around.
vBulletin is very good, but (IMHO) XenForo is even better.
