This form is easy to use due to excellent set of instructions, both when it starts up the first time after you install and activate it (I copied those first instructions into Pages which makes a Custom Contact Forms manual that is searchable and printable. There are also in-place instructions beside the fields when you are setting up the fields. Since the form has so much capability, there are a lot of these, so the first go will take a bit of time just to read the instructions. I love the built in captcha.
The form has lots of flexibility and capabilities, which is why there a lot of instructions. This might be a bit much for a beginning user, but just be prepared to read a bit. I am sure I will be adding style to my forms, and using the other forms I can build with this plugin later on.
But to start with, all I needed was a simple contact me form so future customers could email me. And, right out of the box, I was able to build one in 30 minutes.
