Hi, everyone. Well, I see that it has been almost 3 years since I signed up for this forum, and I guess I am here to stay. I study at a distance, and this website has been a godsent for me over the last few years. Thanks in no small part to you all, I have been able to continue advancing mathematically and am now looking forward to wrapping up my freshman year of college and my first semester of calculus. If you promise to keep the site up, I might even have the courage to enroll in a second semester. Thanks for all of the help.
