Shan,
That was one thing I considered when looking at this software and agree that there is a downfall with no pagination. However, the upsides on this forum compared to others was much better. To read the forum backs from the beginning, you can change the url numbers 1 by 1. This post’s url is Upcoming Changes To MHU and to read post number one from the forum you can change the numbers to:
The first actual post was given an id of 12 so the numbers can be raised from there. We also have a much better search function so you can get search for previous topics or comments on pretty much any subject. Hopefully this will help to fill that gap!
