Can't seem to find or configure a subscription form

Hi there, I am really keen to use this plugin however I ma having what appears to be some very basic issues.
- I can't for the death of me find anywhere where there is a subscription form or the ability to edit the fields for this form.
- I also can't get any form of signup form to work?

Am I missing the obvious?
