Registration email notifications not coming through?

[erinch]

I am running my new vb board around the block before opening it up. I have the settings to require that new users activate via an email link, and then be moderated before joining. The initial email that there is a new user are taking close to half an hour to arrive, to a gmail address, and there are no emails after activation to moderate.

Should I be getting two emails? Is there a way to speed up their arrival?

How do I trouble-shoot this?

I tried searching for the same issue, but couldn't find ... I'm fine with links explaining.

thanks,
Erin Cox-Holmes
