Groups (similar to Google+ Circles) are an easy way to communicate with a specific set of people, instead of sharing everything with everyone all the time.
4. Create a Group
It really is as simple as clicking Create Group in the left column of the Facebook homepage. Doing this will cause a pop-up box to appear, which will ask you to give your group a name, add members, and select the privacy setting for that group. Click Create Group when you are finished.
Once a group is created, you can click Edit Group at the top right of that page to add a description, set up a group e-mail address, and add a photo.
Once you have joined or created a group, you can communicate directly with group members. All members of a group can interact in group chat, regardless of whether they are your friends on Facebook. You can only chat with group members who are online at the time. To start, go to the group and click Chat With Group on the upper-right corner of the page.
6. Share Documents with a Group
Similar to Google Docs, Facebook Docs allows members of a group to write and edit content through the social network. To create a doc, go to your group and click Create Doc on the right. This opens a clean new text-input window with a few simple formatting tools at the top of the page. Select Create Doc, and Facebook will publish the doc to your group. To edit or delete it later, simply click on the document.
7. Poll Members of a Group
In exactly the same way that you create a poll for all Facebook users, you can ask a question to members of a group. Click on the Question icon above your Status window. This will bring up a window where you can ask your question. Then click Add Poll Options to fill in the possible answers. To prevent people from adding their own answers, uncheck the “Allow Anyone to Add Options” box. Then click Ask Question to publicize it to the group.
8. Control Who Can Join a Group
Administrators of a group can personally approve any member who has been added to the group.
To remove a member of the group:
