The email of your username and password is sent as soon as you complete registration. It is also sent as soon as you submit the password reminder form.
If you have not yet received it, it is probably delayed by one of the email servers between yours and ours. Please wait another 30 minutes - 1 hr. or so and see if it comes in.
If you have an anti-spam filter running it may have also been moved to your junk folder or deleted. Please check there as well, or try adding resultsmail.com as an approved sender and use the I can't remember my password link on the login page to have it re-sent.
