Currently, when I fill out the form, I have no idea what's going out to the recipients - perhaps a mad libs-esque design would explain why each field, e.g. party title, is necessary :)
My name is ______(yourself) and this ____(verb) _______(noun)!

My names is atwebb and this is madlibs!
And you'd put the parens on the line, but I'm not sure of the markup for underlining here and feeling lazy.
