Yes, I can understand that you find it a bit confusing moving around in the forum as the icons don't give you the exact instructions to what they are there for. We're working on that.Also I believe you don't have much experience with forums otherwise it'll all seem pretty simple.
As for having the comments higher, this forum has some primary categories which have to be placed where they are more easily accessible. And we always do leave our comments behind after the food.
Your other suggestions have been noted and we'd appreciate any unique ideas from you.
