This is on our list as well. We will have options for 24, 48, 100 and 200 listings per page.
This is always a tricky one and definitely a slippery slope. Prior to us making these changes, there was a DEAFENING roar of "OMG, there are so many threads and things get pushed off the front page so fast that I can't see them. You have to divide things up!"
Now that we have done exactly that, there is the complaint of "OMG, there are so many forums. I can't go to them all and I am missing things!
:lol
This is a damned if you do / damned if you don't situation in which you are never going to please every one but we hope by breaking the forums out a bit, we have helped the situation some and made the previous issues a little easier to handle, while not taking the route we have seen so many forums take where we create 50+ forums that break down subjects into extreme minutia.
