A word to the wise. When you get the e-mail with your login credentials for using the learning labs in the Cisco store, tattoo it to your body. Amazingly, but really not amazing for the CLN, there is NO password reset function in the learning labs.
I don't know why Cisco struggles so mightily with basic website functionality that everyone else in the known universe has had down pat for 10+ years, but they do.
I actually had to open a support case with Cisco, to hopefully, generate a new password. Only 1-2 business days of studying wasted.
Additionally, the CLN will be down for the better part of a day from this Thursday, 5pm, until Friday at 12 noon. That long of a maintenance period is pretty non-standard, but par for the course with the CLN, and so lucky for me to occur during the two weeks I have set aside for this cert push.
Cisco, you make it hard to love you.
