How do I send a pdf for signing

Hi this sounds an easy question but I have been scrambling around reading the seriously bad instructions on the adobe help pages and am no further forward.

I want to send a pdf for two parties to sign. I hit prepare form. The help pages imply I can add seignature emails at this point, I cannot.

It then generates hundreds of little boxes around things. I am hoping I can ignore this, I simply want people to sign the document, I have added the fields to the relevant areas.

Now, how do I send it to recipients, with the esign, because there is nothing I can do here, if I click the esign tab, that are two rotating 'thinking' circles, that do nothing, am I supposed to be putting their emails there?

Cheers
