Never heard of it.  If it's like "Hi5", "My Space", "Art Zone" or anything like that, I'll pass.

Someone sent me an invite and I don't know if it is spam or if it is someone who knows me, but I don't recognize their name or email address.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
