oh i'll try my best ! so, on your group home page you want to go to 'Admin Area'.. and from there there's a section called 'Manage Members'. From there, you select on the left hand side what type of user you want to change the settings for, for example, 'Members' if you only want group members to be able to submit.. and then you can choose how many deviations can be submitted for each folder!! and if they should require approval.
i hope that helps.. but let me know if you have other questions!
