Great feedback, thanks a lot!

All valid points and if this grows into something larger than what I intended it, I'll certainly look into some more advanced/clever ways of handling the email side of things.

Index Ping was intended for top-level domain names only. IE, "Bob" launches a new website and wants to know when it is indexed. Not down to the individual page level, just when he "breaks" in to the index. If people want more granular control over this, I'll take a look.

Cheers!
