I thought I recalled seeing something saying how many of a particular item (ie:  book, cd, dvd) were in circulation or posted on the site as available for trade. I just looked and was not able to find anything. I was wondering if this feature exists? If not how do I suggest it be added?

If you add the item to your reminder list, you then can check your r/l to see how many are posted of that item.  Hope that helps.

It does thank you - that must be where I remember seeing it.

Thanks for asking Melissa, I had been trying to remember also!
