I think it would be great to see sub-categories in the classifieds. Here is the idea. I'm looking for a new canopy in the 230-260 sq. ft. range. Currently I have to search through all of the posted canopies to find some that may match.
It isn't a real big pain after doing it the first time, but it would be nice if items such as canopies had mandatory fields (area, etc.) that could be searched. Similarly, jumpsuits could have height and weight fields that could be searched against.
