Powerful extension. Also a great support. I wanted to put an accept "terms and conditions" box in my form in the Checkbox Group section and that the "terms and conditions" would be a link to the document with those. Support wrote me a line of code to put it in the item section. It worked perfect for my needs. It also integrates perfect with Joomfish. Until now works perfect.

Well this is really a great extension. I had some problems first that were quickly solved by their forums. I think this might be one the most necessaries extensions of Joomla. I am still playing with it but so far I am impressed.
