Now that Creative Commons has an official branch in Second Life, the non-profit's General Counsel, known in-world as Mia Wombat (real life background here) will be giving a public lecture in SL. It's tentatively scheduled for April 20th (I'll post the details when they firm up) but right now, she's requesting suggestions on topics for her to discuss. From the philosophical meaning of free culture to specific legal cases Creative Commons is involved with, her platform's wide open. E-mail her here or if you're already a Resident, visit CC's message board on the Second Life Forums.
The office itself, by the way, is still being built, but a direct SLURL-port to the location is here.
