Each person may use one handle per thread.  This is to help avoid misleading readers.  However, multiple handles are usually allowed when they are being used just to be humorous.

God forbid anyone be mislead on this board, which as all posters know, speaks the truth, the whole truth and nothing but the truth!

I made that mistake my first day posting on the board because I didn't understand that you have to select an alias each time you post, not just once. I will be more careful in the future.

so help you God?
