Character sheet editing?

According to the Roll20 blog post "Data Delve Data Blog", the addition of custom character sheets was added. However, this was only available for mentors. At the end of the post, it says that Sheets would be available for everyone in May. My question is: am I doing something wrong? How do I get to the character sheet editor?

Mentors may use customized sheets. Anyone may use a community sheet. Read all about character sheets in our wiki, and I've excerpted here the section in selecting character sheets: Starting a New Campaign When starting a new campaign, you have the option to choose the Character Sheet you want to use from the handy drop-down available on the New Campaign creation screen. The Character sheet template can be changed after campaign creation as well. If you're making a Campaign that's a copy based on an existing Campaign, the copy will keep all relevant character sheet information to match the original. Finally, you need to click the (I'm Ready, Create Campaign) button to save. For an Existing Campaign To select a character sheet, the GM should navigate to Campaign Settings (My Campaigns > View Details > Campaign Settings). In the Character Sheet Template section, select a template from the dropdown. Mentors can also choose Custom to enter their own HTML and CSS. Finally, you need to click the (Save Changes) button found at the bottom of the screen.

Why Mentors only? Is there a free way to do this?

Mentors can use their own custom sheets that they created themselves. They have an extra option in the campaign settings to import a custom sheet. This is a paid feature that comes with the Mentor level subscription, along with access to the API, more storage, Dynamic Lighting, the Transmogrifier, access to the dev servers, and other goodies. Everyone else is able to use the community-created sheets that are already listed in the drop-down menu of the campaign settings.
