Fields for K2
k2fields is a Joomla! extension that enhances the popular content manager extension K2 providing you an integrated solution to easily develop directory oriented websites such as business directory, review/rating sites, product catalog sites and more.
I will not replicate the available feature set rather invite you to browse to the extension page and read there.
If you have any questions don't hesitate to contact me.
Notice: I am in the process of reorganizing the website and code repo, but all issues (not support request) can be posted in the github issues list in the mean time. Support request are welcome through my websites contact form.
