Ideas:
1) A person could post a picture of themself baring as much as they like and cover the rest of the area in black
2) A person could tell their biggest secret
3) A person could tell someone what they REALLY think of something
4) We could have like a date round, and the three remaining contestants "go out with" each one of us and have to talk in
a) magic talk (always have the word wand in each sentence)
b) or send them a letter saying what they REALLY think
etc.
This one doesn't have to necessarily be to do with magic, just courage
Does any one have any preference?
