We are trying to make a social community. We would like to add a business directory plugin for related businesses. We like it to be for free, but in return to get a link back... So, I have seen very often in blog directories that you first have to put a link to the site in your blog and after you're welcome to add your blog in the directory. This is what we would like for our business directory. Is this possible with WordPress Business Directory plugin? Or does anyone know of any other plugin with this option? Or what do we need to do...?
