If you are incorrect or unsure of yourself, we generally remove them. People who post questions here are looking for ways to find good, solid, correct information. No guesswork.
Who is "we"?
The various tutors here.
How does one become a tutor?
Post good solid answers (such as what you did here >> http://www.jiskha.com/display.cgi?id=1285177656 ) for several weeks so the tutors in the subject(s) you specialize in get a sense about how good your knowledge is, how well you explain things, how reliable you are, etc.
If you get an invitation to email a tutor here, you'll know you did well.
