The mailer now has vote buttons on email. If you have enabled emails on new posts from subscribed users or groups, you can click on the vote buttons in your email to quickly vote on content.
Ok, it actually isn't working 100% yet. Vote buttons are missing in email!
I'm guessing you would need to have remote images etc turned on for this to work via email.
Yeah, I'm using a custom font for the arrows, so I need to re-work that to embed the font in the email as data, or use an image...
