Mark has announced the launch for OCS on his blog. If you are interested in coming along to the event in Vinopolis, you can sign up at the launch site.  I notice that Carston Sorensen is speaking at it - I did some flexible working studies with Carston from the London School of Economics - he is a good speaker and knows his stuff.

He also makes some good points about how useful Groove has been in organising the launch.
