Hi Trailhead SUPPORTS / Community!

One of our clients is experiencing issue when trying to login in Trailhead. 

"I am unable to login to trailhead. I think I may have turned the emails off. When I select forgot password no email comes through to my inbox. my email address is charlene.johnson188@ymail.com. My username is charlene.johnson188@ymail.com"

She has also posted here earlier and has not yet to get any reply. Please help her proceed with the next steps.

Thanks!
