No send address

You must be logged in to send emails to other users.

If you are logged in, this means that your email address in your preferences is either not sent correctly, or not verified. Visit the preferences page, click on User Profile and scroll down until you see the section Email options. Make sure that a valid email address is set there, and, if necessary, click on Confirm your email address.

See the screenshot below to see what an unverified email address looks like.
