Superb support and well thought-of features

I started with the free plugin and then bought the extensions pro package. Even the free plugin has most of the basic features. The features of every extension are well designed and most of the things can be done through configuration/settings. To top that up, Steven responds promptly to every ticket and is very patient in replying to queries.
I would definitely recommend Connections (Free/Pro) to those who are looking for a directory plugin.
