Let me make this clear.
It's not only you. There were a few other posts.
I personally use the site for things other than just selling my parts. I've been on this site since 2006/7 and I contribute where I can. Mostly I do this via pm when people need help with their cars on the forum. I come here to read about whats going on with our cars, as well learn about my car when I need to.
If you have a problem with selling your parts either lower the prices OR make an area in your signature with your parts for sale THEN contribute to the forum. You've been here since 2010 and have 4,130 posts which averages to 4.5 posts a day....make a thread with all of your parts you have sitting around and bump it.
Follow forum rules. Simple as pie.
