Adding an application form to a Facebook group

1. Are there any restrictions on how big the group has to be before you can add an application form?

2. Where can i find instructions IN EVERYDAY LANGAUGE PLEASE - how to do this

Please check also on the user guide : Adding a Contact Form to Your Facebook Page

Let us know if you need further assistance on this.

My question was about adding an application form to a FAcebook GROUP, not a
page.

Hi there,

Unfortunately, we do not have that specific feature as of the moment, however, if you wish that only a specific Facebook group will only able to access the form, you may post/show the Direct Form Link on the group. 

Here is the guide to get the Direct Form Link: https://www.jotform.com/help/401-Where-to-Find-My-Form-URL

You may also add a Password on the form as an added protection or exclusivity to your Form access. 

Here is the guide for Setting up Password Protection: https://www.jotform.com/help/579-How-to-Password-Protect-a-Form

I hope that helps.

Best.
