CREATE A POLL Hiding in plain sight above the box to enter status updates is a Question button. Posting a question looks just like posting an update, except that it takes the first three answers from your friends and turns them into a poll to keep the discussion focused. You can also set up the poll with your own answers, or add more to those Facebook creates.
COLLABORATE ON A DOCUMENT Within a Group page, click on Docs at the top of the page and then the Create a Doc button on the right-hand side to create a text-only document that everyone in the group can edit. When you save the document, it will be posted to the group’s feed, just like a status update, with an Edit button in the upper-right corner. To see previous revisions, click Recent Changes.
