Thanks for the suggestion. We usually don't put new forums unless there's a really good reason for it, and some other is bursting at the seams. With that said, we did do some rearranging recently and split a few, so they do seem less traversed now. However, its not proportionate with the amount of time the other forums existed, so its not comparing apples with apples.
If you have a particular exact suggestion please let me know what you think is really out of place and the mods and admins will review your suggestion. Thanks for your suggestion, means a lot to us. We like dedicated members that want to help the community.
