Hi
I'm helping organise the Nine Worlds Convention (nineworlds.co.uk) in London 9th-11th August. In particular I'm in charge of the open culture track, and I'm looking for people to talk about or demo open source games. Iwan suggested this would be a good place to ask.
We are a new convention and entirely volunteer run. We're basing ourselves on a sci-fi con, but looking to be a lot broader than that including all sorts of geek culture.
If anyone is interested in giving a talk, being on a panel or running a demo, either email me (open@nineworlds.co.uk), PM me or reply here.
Thanks
James
