Hi,
I have created a new group on the KionUp website for those interested in machinima, either by watching, discussion, tips and tricks, and or participating.
http://www.koinup.com/group/sl-machinima/
Anyone is free to join and offer their thoughts, work, tips and tricks, and as always feedback is encouraged.
I have included the OpenSim platform as there are many simularities. It is also a new growth market.
