Sandbox Question

is it ok to post something for sale/trade in the sandbox area?

First off, before I answer, I am NOT on staff on this site. (or any other one for that matter.

BUT, I have seen numerous other For sale posts placed in the Sandbox such as the current one from Brooke for the washer/dryer.

I've seen providers offering incall stuff to other providers in the Sandbox when they are retiring and I've also seen numerous Requests and ISO threads when someone is looking for something they need or want.

thanks........i'll see what happens
