Re: Confused about how to get visitors to my forums.
have you published any content on the forum yourself? You can't expect a forum to grow from scratch with only member generated content. That's usually a second step. First you need to attract potential members to it. Sometimes, starting a debate on a few controversial topics or posting queries is a good first step. This will instigate initial participation and you will need to maintain the rhythm even if its only a couple of members participating at that point.
Also, 3 weeks is really nothing! it can take up to three to six months before a forum starts picking up. This is more so if you're starting a very targetted forum for a specific topic. You are basically inviting a very narrow niche of online users... so you need even more time.
