Having to click view source is so drag and drop doesn't accidentally highlight text. I'll make it so that only applies on the pages with drag and drop.

I've gotten a number of replies about the email invitation. I am looking into that currently (one monitor is that code, the other is HN). It's absolutely a bug if it doesn't do what you, the user, expect -- even if it's what we intended. However, this seems like a true bug, probably an overstrict email validation regex.
