I am also a new user having this problem. I just created a job posting but I cannot save it until I have verified my email address. I have quadruple checked that the email has been spelled correctly, I have sent emails to the address so I know it's not a problem on that end, and out of frustration I tried opening a new email account specifically to bypass this problem but I'm being told that the brand NEW address is already in use.
I've resent the verification email more times than I can count and still have no idea where it's being sent to or if it's being sent at all. I would appreciate any further help on this matter as I feel like I've exhausted my options.
