What is JotForm?
JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Yes, that is correct that the Free Plan only allows up to 100 Submissions per month.
If you go over the submission limit your account will be placed into an "overlimit" status and your forms become disabled until either you upgrade or wait for a monthly reset which happens on the first of the month for free accounts.
You can see our pricing plan differences here on our pricing page - http://www.jotform.com/pricing
Also, I would like to point out that we do offer free extra submissions to increase your limits to a little more than doubled for free accounts found here http://www.jotform.com/myaccount/getMore.
