I apologize to anyone who's thread I have hijacked. The times I had caught myself doing it I had apologized directly to the owner of the thread. But in reading this, I have come to realize that I owe more apologies. Please believe me when I say I never did it with malicious intent. "Side tangents" are something that I have participated in and did not think enough about before submitting replies. I will be more aware of this in the future.
