If you're not getting email notifications you should look into your SPAM/JUNK and other filter settings (both yours locally, your providers, etc). 

I'm happy to resend, check the status, and manually approve your email if you can't figure out why you're not getting email from DME Resources.

Of course you can also associate a different email address with your account, where you may have more control over those things if you'd like; simply edit your profile settings.
