I just released a big internal update to the site. This doesn't mean much for you, but the site might be a little unstable. Please don't hesitate to message or email me if you see bugs or weird things.
If you're curious, NearbyGamers used to send email via Mandrill, but that service is shutting down. Moving to Postmark meant catching up to a lot of new code, so the site's moved from Rails 3 to Rails 4.
My only serious concern is that updating to a new email service might make GMail or other email providers nervous that email via NearbyGamers is spam. I've done all the configuration I can (SPF + DKIM records) but maybe keep an eye on your spam folder for the next month or so.
