qGalleryPro is a great component. The issue is that their customer support is what lacks in this component. To get anyone to respond to an email or forum request is impossible. They did great stuff connecting to FB but honestly unless you are a developer that can finish what NetqCreative has done good luck!
JTAG Calendar is simple to use and flexible to customize. The JTAG Support group has been excellent at fixing bugs, responding to issues and also taking feedback to make the product even better. Worth the money!
PreachIt is very customizable! This is the most valuable Joomla extension for our web site. I used to have to use three different applications and spend over 20 minutes of time to accomplish what PreachIt does for me in a 5 minute posting of a new message. I appreciate Paul and his contribution to the Kingdom!
