Tiny, pri-3 front end bug, but thought I'd report it. (Bugs are getting harder to find! Yay!) When using right-click-"copy email address" from a user's profile, it's grabbing an extra space on the front of the email address. When you paste, you get %20 on the front of the address, which you have to manually delete before you can send. Only tested in Chrome.
Clicking on the link generates an email in the email client, which seems to handle the space fine, so it's just the right-click-copy that's broken. Like I said, not a big deal :)
