how can i share a form with someone else and let them edit as well?

I want to share my form with prav9884@gmail

Hi,

You can share the form with them as a subuser:

This will allow you to give them access to only the forms and/or submissions that you would like. 

If you have any further questions, let us know and we will be happy to help.
