I can't understand this obsession and paranoia that I have noticed on different posts from certain people about aliases.
As been mentioned, very rarely does somebody use their own name, and rightly so for privacy and security.
As a newcomer I have been accused of this, without foundation.
I heard a story about a newcomer who joined a group and was hounded out of that group, was called a d**k head amongst other things from the "stand in" moderator at the time, this is not setting a good example and a complete misuse of their position.
Apparently the new member left the group and deleted their account with SL.
I would urge SL to investigate this inappropriate harassment if they want to make this site a welcoming place and to encourage more new members.
