I was wondering if anyone had any experience (or advice) on running a social networking site catered to a specific interest or hobby? Like for Bungee jumping enthusiasts to meet up & converse for example. If so, how was the foundation of the site created? Because I am guessing the majority have to use a 'white label' type program like SocialEngine.net for example and just incorporate your theme, logo..etc. If you have any advice on what steps you have taken or would take if you were to go down this road please let me know I would love to hear about it! Thanks, Marcus.
