thanks, joltin. i remember reading somewhere that we should limit the amount posted to 400 words, as some authors don't like having their entire article copied. they (or their advertisers) may get paid based on how many hits their web page gets. so if their article is copied in its entirety, they may stop publishing their work for free, and then we all lose out. so i post what i think is the most relevant portion, and sometimes i try to say something intelligent about it, and then i normally provide a link to the original page for anyone who wants to read the entire work. i think that works out best for all of us.
