The wrong way is as a crutch for bad design.
An on-site tutorial is not the solution to a complicated design.
If it’s too complicated to use, improve the design.
Most members simply click through a website tutorial anyway.
A better approach is to trigger a tutorial by an event.
i.e. After a member reaches a certain gamification level, has been a member for a year, or earned a special badge, they gain new powers. Here a pop-up/on-site tutorial can show them what they now have access to and how to use it.
Now you’re creating pop-ups people are excited to see and actually read.
Bonus tip – hold some permissions back from newcomers so you can surprise them with new permissions later.
