Their emails to me do not appear in my Inbox or Spam folder. enworld.org lists this as a known issue but has no recommendations other than using another email provider!

It's a widely used forum (particularly for D&D players) & I'd like to be able to register there without resorting to some other email address. This is not the only site I've had this issue with.

How can I make sure emails from enworld.org & other sites are received?!?
