To use the forms on the Submit Info and Find Info pages, remember that the information stored here is VERY public, and as such, well, you've been warned. 
The purpose of this feature is to allow people to contact each other when they have something in common. For instance, there are fields for school info so if you attended Grover Washington High School, you could search for fellow alumni by searching on that field value. Or if you were in the Class of 89, well, any field will work. Enter it in normal values, don't get too creative or it does no good to anyone!
