It is a great idea to claim the Facebook Community Page. You are even able to combine them with an existing Facebook Fan Page if you have one.
Here are the steps to claim the Community Page:
- Head to the url of your Community Page
- Click on the drop down arrow in the upper right hand corner next to what looks like a "gear". The "gear" is to the right of Add to Map, Know the Owner, etc.
- Click "Is this your business"
- Follow the instructions provided by Facebook to claim your Community Page and combine it with your Facebook Fan Page (recommended)
