Hi there :)
Like many other people who use this plugin, it's purpose on my website is to act as a business directory and not an ad plugin. (Like Gumtree)
I read somewhere on the AWPCP website not long ago that support for a comments system and rating system module is in development at the moment. I'd basically like to know the estimated ETA for this as I pretty much need it now or ASAP.
If the release date is soon, there is the featured ads module I would like to purchase as well, however I am not purchasing the featured ads module if I have to wait over a month for the comments & ratings system to be released.
This is a fantastic plugin and I'd hate to have so switch to one that isn't as good and easy to use but supports these things.
