Is it necessary to use SSL submissions?

If I check off the secure submissions will I still loose my submissions?  We are a nonprofit and we dont need that really.

No, you should be able to receive submissions in your form without the use of SSL.
I've checked your account and noticed that you've already reached the 10 SSL submissions per month limit that is set for free accounts.

So, I've reset the counter so you can still receive submissions. But you should note that this is something we're allowed to do one time per account.

Please verify that you're not using SSL submissions to avoid any problems with your forms.
