You should be able to submit a query without having to enter your email address first. This was a deal breaker for me, because I don't like giving out my email address to websites I know nothing about. At least show me that by giving you my email address and potentially getting spammed I'm going to get something cool out of it.

Goos point! I changed it so that if an email address is not given it will just do a search on the current deals in the index.

Thanks for the feedback.
