Hi! A first-timer here, I wanted to make some changes to my team's submission:

(1) change the title of our project to include the language like I saw others do in square brackets,

(2) add screenshots,

and (3) add team members as admins.

Are such changes allowed during the rating phase? 

Some of my team members want to rate the submissions. Will they be able to do so if they are added as contributors at this point or should this have been done before the submission? EDIT: tried, it worked!

Thank you in advance for clarifications!
