I was looking for people involved in socialnetworking on openbc, when I found Christoph Baumann's profile. I got in touch and he replied a couple of hours later, and invited me to join the GastroLounge.
GL is a social network dedicated to the Hospitality industry
"Gastrolounge.com is the network of relationships for companies and their employees in the Hospitality Industry and their B2B partners."
GL utilizes openbc's technology ("white label" service)
The platform is robust and comprehensive (it is not very nice though)
They license openbc's technology: it is a good choice, as I believe openbc is one of the most advanced online networks in terms of interface/features.
