Thanks blacknight..

Bar the clean design.. not a whole lot!)

A thing i'm slowly getting around to do is to have each category tailored for its subject. Example: when posting a car you'll have fields for year, engine, mileage etc. For property you'll have fields for bedrooms, garage etc etc. (so far i've only done this for autos).

Also considering a PMS service to allow messaging between seller and buyer.

I have a few other little ideas i'd consider. I'd like to have it as community based as possible and all that goes with that.
