Right now I am using the medium of Second Life to Brainstorm about all the familiar topics on Life Extension. It is my intent to keep doing this for the foreseeable future. I am well aware that SL is not to everyone's taste as a medium of choice to "communicate" or "interact" virtually but somehow it works for me. I would invite interested parties to join us every sunday and enter SL. My intent is to slowly bootstrap these talks to an attendance of 40+ in the next months. That's pretty big even for a weekly "meat" event, and the quality of talk during these events (while meandering) is often of high quality.
You can find more details on content and past events here. The topics often lean heavily towards the transhumanist angle. Also, these events can be quite outspoken.

If you aren't sure on how to enter SL, I suggest you have a look at some online (youtube) tutorials. There are many. To get an account, register here. The recommended SL client (Firestorm) you can download here. Creating an interactivity avatar takes about an hour, getting used to the interface might be a little more daunting.
It's not everyone's cup of tea, but if you try it might end up surprising you.
