How do I Share My Form

I have created a reference form for our summer attendee's It has not been proofed so Im not ready to publish. I am wondering however if when I am ready to publish - how I go about doing that...if I can just share the link and people can follow it and fill it out or if this has to be embedded? Do you host the form? Were do the submissions go? Do you host the form? Does or website host the form. Do I need a membership for this to work?
