There are two types of users – Users with free accounts and users with paid accounts. The workflow is slightly different for each user type.
Paid users will generally use the SIGN UP link at the top of the screen.
Free users will use a REGISTER link. The register link is currently on the SIGN IN page.
If a free user is logged in and wish to sign up for a paid membership level, they can go to the PRICING page.
If you’d like to keep the workflow the same, you can can create a FREE membership level with a price of zero dollars.
