I like to answer more introductory questions, especially about basic calculus. The issues are usually more subtle.

I also enjoy enumerative combinatorics. I have finished my MS and am currently an instructor and the director of some of the math program for undergrads at my school. My master's thesis dealt with abelian difference sets, their uses and constructions, existence proofs, and such. I may do my doctorate someday, but we shall see. I am tired and old, and I do not like formal academia very much.

I also like jazz, my dog, and my wife. That is not an ordered list.

Just because you are good at math does not imply that your opinions about math are objective, important, or even well-reasoned. Be humble. You can be wrong. You probably are. And for god's sake, be more friendly and welcoming. This site is colder than deep space.
