Hi,
We seem to encounter that kind of people everywhere. I am also a
low profile guy in class, and I was ALSO required to do a film
project (I'm not in RP though), AND I had 2 such members in my
group.
It's hard to let other people think that they are leechers and all
that; all in all it just sucks.
What we usually do is continue asking him to do his part and then
boot him out as a team and watch his astonished face.
