When we start a forum, we can't go full-force with advertising, because you'll be promoting an essentially empty community, and it will be ineffective. So where do you get your first group of members from? Personal friends? Private invites?
I'm guessing most of mine came from the org. It was the only place at the time I posted my graphics on.
This is what I did. But at some point they want to tell there friends which I said 'ok' after the core group joined. I wanted the first people to join to set the tone of the forum.
I usually start on vBcom/org in addition to inviting people. When I'm ready I can start the advertising on specific niche sites related to my forum.
inviting a few friends to come in and post a few threads, get discussions going, and then ask them to invite a few friends and then once we have about 5 threads in every section, with a few replies in each, then we can start advertising
