Ok this is an offical complaint! When was the decision made that it would a good idea to not include digital signatures as a integrated function of forms? What is the soul purpose of creating a form? Do you think that people just like to click radio buttons and check boxes for fun?
I was really enjoying the fact that I could just use one account and have a very nice creative suite solution. But I have to add here and add there and get nicked and dimed to death.
Jotforms works better than Form Central and has signatures built in with no extra cost.
Unless you have a good excuse I'll be leaving form central.
