Right door? Employers sign in at /admin/login. The candidate sign-in is separate and won't accept an employer account.
Forgot the password? If the sign-in page offers an e-mailed sign-in link, use it and set a new password once you're in. Otherwise write to support@offerrole.com from your work address.
Invitation not working? Invitation links only work for the address they were sent to and expire after 7 days. Ask an Owner or Admin to invite you again.
Too many attempts? Repeated failures are slowed down for a short while by the firewall; wait a few minutes and try again.
Posting and reviewing are free. Every stage, e-mail and export described here is in the console from the first sign-in.
