That's really cool of you guys. I apologize for doubling my email, because I saw this right after.

Your product is slick. I can see myself convincing a customer to use this, which is not something I could say for Dropbox.

what do you mean, email@domain.com +hn?

Enter in email+hn@domain.com and we'll give you access right away.

Gmail allows tagging at the end of the address like me+tag@gmail.com. This is what he is referring to.

This is in the email RFC 5322, it's not GMail.

What do you mean? Just because it's in the standards doesn't mean they are treated as the same address, does it?

I don't see anywhere that myaddress@email.com and myaddress#this@email.com must send to the same mailbox. I only see that an address must "[contain] a locally interpreted string followed by the at-sign character."

Of course, this means that you can use - or ~ or # in your address but they don't have to be treated (and probably aren't) treated as the same address by most email systems.

Done. Thanks!
