Which of the following are you willing to share about yourself on online forums such as this one?
Your real name?
First name only.
Your city of residence?
I'll give the state and region within the state.
Pictures of you?
Yes but I usually only put them up for a limited time and nothing too embarrasing.
Your email address?
Only if I know you well.
Your IM username?
Again, only if I know you well and want to establish a deeper friendship.
