Tutorials must be created by you and your own idea.
If you got idea from elsewhere and revised your own version of tutorial, please include reference and credit original authors.
For example if you found a Photoshop tutorial and wanted to write a GIMP version, you must credit the original Photoshop tutorial.
Tin, I do not understand. If not in another group, what would I change "Script Tester" to?
Since you're in Script Testers and Tutorial Creators Group.
If you wish your group rank to show as Tutorial Creator instead of Script Tester, In Control User Panel, under UserGroups tab, you can click on the group you'd like to make default and then click the "Change default group" button, and your rank will show as that default group.
If you're happy with it showing Script Tester right now then you don't need to change anything.
But once you're in more than on group you can choose which one to show as default.
