If you need to resend login details to a participant, follow the instructions found here.
You can also direct participants who have been previously invited to simply go www.blanchardexchange.com where they can enter their email address along with the password they previously set.
Note - Blanchard Exchange does not include passwords in any emails for security purposes. If you have a participant who does not know their password, please have them go to www.blanchardexchange.com and click the "Forgot password?" link under the "Sign In" button. Once they enter their email address and click on "Reset Password", a link will be emailed to them allowing them to reset their password for their Blanchard Exchange account.
