I've thought about this a little bit more since Tormie's last post; and I decided to clarify my previous statement.
If there was a "PosetteForever Club" on/in Second Life, I probably would visit it once or twice, just to see what Tormie had created in this new medium.
But; virtual communities are not interesting to me. I have a "MySpace" page, and rarely visit it (I'm waaay behind in updating my musical creations there...); I have an "ArtZone" page, and haven't even taken the time to add any art or information to it; I do not accept or send "Instant Messages" or "Text Messages"; and I do not visit chatrooms.
So; to answer the title question... No, I do not Second Life.
