How do you make people your favorite stripcreator authors so they can be at the bottom of the screen?

go to edit account and it will guid you through there

That feature is under "edit account" at the top of the screen. Go to "Favorites" once you're there, and enter the authors in the box. (Use a separate line for each one.)

This question really should be added to the FAQ.

It can go next to "How do I log in?".
