What methods should new webmasters use to promote their forum? The same guidelines apply to running a site and promoting it as apply to writing good software. Keep your focus narrow and concentrate on doing a few things really well rather than spreading yourself too thinly and doing a lot of things in a mediocre fashion. Engage with and foster your enthusiasts, and they will do your promotion for you.

It's great to get an insight into the minds behind XenForo. It helps us to communicate with you both and actually know the direction of the software, it's very comforting. Also seeing your comments on the software and seeing how confident you are about the MVC principles and the ease of use makes us all very confident that you both have created a much-needed piece of software - for all of us.
