Hm, there aren't that many, actually:
 * Age
 * Birthday
 * Height
 * Weight
 * Foot Length
 * Rc level
 * Class
 * Division
 * Kanji if they become available, but the name was already known before (can happen if the name was written in Katakana when the character was introduced).

I'm not sure about alias, gender, rank, blood type and honors, but I think we should forbid editing these as their reveal might actually turn out be important.
