I have been using Chronoforms for almost a year now and I am glad I choose this one. It can do sooo much more than a simple "Contact Us" page. Max and Bob have given me and thousands of others truly great support and both of them are very responsive to your questions weather submitted on the forums and/or through email. This extension is kept up to date quickly too which is great.
With Chronoforms, you can quickly create a simple contact form or with a little coding knowledge, you can create super creative and very useful forms that really benefit both the end user and the webmaster. Easily display info from the database for a particular user or in general.
If you are looking for a simple but powerful and very capable form builder, this is it. I have tried a few others and, well, this is the best in my opinion. Thank you Chronoengine for your great work!!!
