First lets talk about the component. I have tried other Form components out there and not only were they convoluted but I never could get them to work. The first time I created a form using RSForm I didnt need one stitch of help.
Once I started getting the hang of things I would post a question or two and I always received a response in about 12 to 24 hours (or faster).
When I had a form that was incredibly challenging they continued to help and never once was rude even after my countless messages.
If you are looking for a easy to use extremely robust form, look no further... RSJoomla has it and much more!
We were users of Acajoom (the free version) and we wanted to upgrade to JNews when moving to Joomla 2.5.6. After looking over the differences between the free version and the pro version we decided to take the plunge.
Since then we have been extremely happy. Support (via tickets AND live chat) have been amazing. I have asked several questions and was treated with the utmost respect each time; no question was too trivial.
If you are looking for a good newsletter option, check out Joobi... you will not be disappointed.
Personally, I think Joomla! should use this as a built in option to Joomla. I tried using the fairly new option in global configuration for offline installs but it didnt look anywhere nearly as nice as the Coming Soon extension.
Thank you Pavel for a great extension and the great support. A rare thing to see with a non-commercial version.
