But what does the link do?

EDIT: Nevermind, I get it now. I think the idea has some promise, but I'd work on making things more clear on the main page.

Maybe have three small screenshots showing the process:

- An image of an email window with the link pasted in along with event info.

- An image of what someone sees when they click the link.

- And an image of the page where you view their responses.

It would also be cool if the invite link page included everyone's responses.

One link is used by your friends to tell you their response and the other summarizes their responses for you to review.
