I have used both the Enhanced Contacts and MooFaq Components and both are outstanding and the support unparalleled! Installation is always straight forward and rock solid. I had an issue due to some features of the Gantry Library and a Rockettheme template. Sent a port email request and had the answer is minutes.
The developer is responsive, courteous, and insures a resolution to the issue in the rare event there is one.
Thanks for the support and GREAT products!
