There's a documentary about virtual world to real world romances in the works and Back2back, the documentary company developing it, are looking for participants based in the UK to share their stories about Second Life, World of Warcraft and beyond.
According to this quote straight from the casting call shared by Linden Lab, Back2back seem like they're interested in telling a fairly flattering story about virtual romances:
The programme is a completely positive documentation of these relationships, where we look at relationships that have blossomed through online gaming, with players falling in love through their avatars and going on to have meaningful, committed relationships in the real world. It will look at unconventional relationships in a counterintuitive way, overturning many of our prejudices and misconceptions with honest storytelling. It will challenge us to realise that committed, successful relationships can embrace the unusual.
If you'd be interested in participating, or know someone who would be, get all the details from the original post from Linden Lab here.
