Posting on other similar boards is a scum bag move and really irks me! I can't believe anyone here would advocate or look past this kind of behavior.

You know full well the many hours you put into your site. How would you feel if someone came along and put up that kind of post on your board?

The answer to the original question?

Build it and they will come.

Come up with a niche site/community that isn't out there already.

In my case, it's a fishing board focused on one state.

Or, if it's out there already, do it better than the other guy.

When it comes time to promoting your site, use ethical means. In the end, you'll be far better off.

Also, there is nothing more powerful than word of mouth. Keep focusing on making your community good, and the members will help do the promotion work for you.

Finally, think in terms of months and years, not days and weeks when you want to build your community.
