I appreciate all of the advice...It was way more than I ever expected,
but then again, that is what makes the linux community so unique.  As
for my questioning of MS, they do suck...and I am an English minor, so
don't worry 'bout me and communicating in the business world....I try
to make my posts informal and easy to read....ty again for all the
