If you do start a forum, it is a good idea to have a Facebook page too. I agree with the member above who said visitors are more responsive to your facebook page. That said, not everything is suited to facebook, and users might prefer a forum in the topic is something they don't want the world knowing they are chatting about. You should also consider your traffic. If you do have a forum, and it's empty, that tends to make users assume that nobody else is visiting your website, and they should leave and go somewhere popular. This is a key reason things go viral. People want to be included in popular things. One approach is to make a Facebook page, and a private forum. Focus on driving traffic to your FB page, but invite your elite visitors to the forum by offering something private. This might be information or tools that others cannot obtain. Make the forum obtainable by everyone, but not immediately accessible. People want to feel special. ... Once you have a good core group posting regularly in your forum, then wrangle some volunteer moderators and give them the ability to accept new members. Soon you will have moderators who are loose with the rules and some who are strict. At some point the forums will have enough activity to offer a section for the public and one for the elites. Forums will grow and do well if you plan ahead.If you don't have any offering that would appeal to your visitors (a reason to be elite and get involved) then just stick with the FB page. Be sure to load it up with some people and post regularly. Even FB pages take some effort to be successful.I hope this helps.
