Overview
Your responsibilities within a group are not yet defined, but you should definitely not see this as a problem -- because you have the opportunity to create your own role now, and you can take on as much or as little as you want. And you can decide whether you want a high-profile role or a behind-the-scenes one. There is no wrong or right decision -- just listen to your gut, weigh the pros and cons of becoming more involved, and take it from there.
