Categorize the classified section!

[fishmonkey]

I was looking for stuff on there and it was impossible to find anything! its just a big jumble of stuff. it would be nice if you could make it so that people could put there threads in different categories. so you could go to a livestock section, then click on fish, and then you could have stuff about fish instead of everything. or if you were looking for Metal Halide lighting you could go to equipment and then go to lighting and then go to Metal Halide and then there would be stuff of people selling Metal Halide lighting.

PLEASE CATEGORIZE THE CLASSIFIEDS FOR EASE OF USE! THANK YOU!
