|Using External Groups / Contributing to a Community|
Don't be fooled. You're a crucial part of a community that needs your input. You may not be a community member, but someone in the community invited you because they knew you'd add value. The benefit to being an external contributor is that you only see the parts of the community that affect you. You don't have to worry about seeing anything you shouldn't.
Your role is to help the community reach outside of its circle, and to share knowledge so both you and other group members can work together successfully and efficiently. You can feel free to ask questions in your group(s) and to post and comment on documents and discussions. When you become part of the conversation, you'll improve how work gets done.
