O.K. Silly Guy How can I send you a mssg on your B'day when ya don't have the blanc filled in ?
Do you mean you want to now how to send a PM without a subject?
If so, you have to have something in the subject box.
You could type a dash
(-) in the subject field or you could hold down "Alt" and type "255" with the number-pad.
This will make a special blank space.
For some reason, this special space can be the subject but the spacebar space cannot.
