"I need the world to last another century and a half, not just see me to happy old age. " - David Mitchell, Washington Post Interview (Aug. 2004)

I took the time to help you, please take the time to help me. Send some good karma my way.

Stop spamming & plagiarism on the boards to maintain board integrity! Use the "report abuse link" on the post and rate their posts as N/A. Abusers keep people from getting the answers they need and steal karma points from the hard-working posters who deserve them. Give credit where credit is due! Cut & paste does not a solution make!

Rules of Thumbs for New Posters:
1. Post the complete question. Never just ask: How do you do problem 10 in Stewart? or you will not get help.
2. Don't post multiple questions in one post. Only exception: Followup posts to clarify the original question or to understand answers.
3. Always rate. Rate the best answer. This may not always be the answer given by the first poster. Do not give good karma to posts that give only answers w/o explanations. Note that even posts that are unrelated to the questions must be rated, even if it is N/A, or they will affect your respect score.
4. Cutting & pasting solutions of other posters is karma point abuse. Work to maintain board integrity!
