When I click the link to sign up, the site wants me to sign in again. When I attempt to sign in with my RPS e-mail and password, it states " Invalid login attempt"

Am I doing something wrong?

When you register on the website it should send you a confirmation email which you may have missed - as a result your login was not verified and that is I think why you are seeing this. I just set the flag on your account email so I think it should work now.

Let me know if not and I can call you to go through it with you on line


Where will the recorded classes be located? I purchased the 12 series pass the day after the first class and I have not been able to locate the recorded version.


It will be posted today James

Hi Alan,

Where do I find the link for the recording surface modeling class? I can’t seem to find it on this page.


Hey Alex,

I will send you an e-mail in a moment with the link. I sent an e-mail last week to attendees, but got an e-mail yesterday saying the bulk send kicked back from my account! My apologies.



I am trying to find the link for the recorded classses also. Can someone point me in the right direction?


Hi Dane,

On the front page of the community, scroll down until you see “TBC Mini Class Archive”. Each class should show up below that section with a lock icon and the name of the class. Click the one you would like to view, and then click on the class header within the landing page to view the content.

Hope this helps, thanks!
