I agree and have posted quite a few wanted ads. BUT BEWARE!!! You will get scammers responding to your ads. They'll send you stupid e-mails, like...
"I have what you're looking for! Why don't you call me at ***-**8_****. " Typically, just to make sure it IS a scammer, I'll respond to the e-mail with a polite request for more info. and some photos of the item. They usually don't respond again. So, just a reminded to those who use CL in any capacity that there are spammers and scammers that frequent the wanted ads too.
