I've been using Data Springs Collection since it's first release. As with most custom modules there are intermittent problems but with feedback and some of the best module tech support around they have all been resolved.
Some of Chad's modules are a must have (Dynamic Registration/Forms/Tailored HTML/Opt In Email)...
They have always provided us either a patch (at no cost)...or significant discounts for upgrades when the problems were related to a different DNN release/environment than the one the module was developed for.
Excellent module...does everything Mandeeps says and it is very easy to use. Really makes adding tips to your site as easy as adding text to a standard HTML/Text module.
Outstanding customer support...
I've been using Module Wrapper for about six months now and version 4.0 since its release. This is a must have module for anyone setting up a portal. This one of my most important modules and it works as advertised. There are a lot of options but my favorite is wrapping my RSS news feeds and providing a manual scroll bar.
This is an excellent module. I've used it extensively through out my site and it really makes arranging modules evenly in a table effortlessly. The scroll or slide option is great.
