From the Playtraq Blog:
First off, we’ve introduced email notifications. You can signup to be notified of emails of new game releases for each platform. You can specify which platforms you wish to be notified so if you’re wanting to get emailed the latest Xbox 360 and PC releases, you can! Hit the subscribe button and sign up to any platform (Don’t worry, you can change your preferences at any time as well as unsubscribe).
I’ve been hard at work on updates to Playtraq the last week and have implemented email notifications so you can subscribe via email as well as RSS, calendar or through the website.
