So far I have found every form I have needed. The only problem I have is that I cannot print directly from the website. When I try to print I get blank pages.

This program is awesome. A little difficult to look up forms at times - but overall experience was fantastic and the finished product looks clean and professional.

An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC

I was dealing with California DMV forms and no where did it tell me to send our Florida Statutes showing the towing procedures for a private property tow. They rejected my pkg. & sent letter, delaying processing 2 mths. Very frustrating to say the least.

I like being able to fill in forms from online. $72 is too much for this as I only pay $30 for several other internet programs. There should be a refund.

A bit difficult to navigate…
A bit difficult to navigate through/enter updates unless you use this on a regular basis. Once the memory kicks in, it's a GREAT tool for making easy changes/adding necessary information.

Accidentally subscribed after the free trial but the customer service team was super helpful at refunding.

How do I bypass field validation?
If you are building your own form, you need to remove '#required' → TRUE, from field to bypass validation or assign FALSE value. Now you can do the same for existing form by alter the form using hook_alter_form and unset required attribute or assign FALSE value.
What is required option in Google forms?
Make Questions Required Instead, it will make any newly created questions as Required, hopefully saving you from one more button to click. If you create a question that is not required, such as Any questions?, then simply click on the required option on the specific question, and it will no longer be required.
How do I limit a Google form?
Now, search for Form Limiter, click on the Plus button, and give the necessary permission. To limit responses, create your form, click on the Add-ons button and select fromLimiter. Next, pick the limit type. If you want to stop accepting responses after a certain time, the date and time is the option to go with.
