Hi Mari-San. To answer your question directly, I don't believe there is any such list. If you continue to follow this forum for a while, you'll quickly develop a feel for what the other members perceive to be good and not-so-good practices for documenting your profiles. Most of us would not remove data from a profile unless it's something totally useless -- like, for example, bookkeeping data from other web sites that sometimes gets imported with GEDCOM files, but has no meaning on this site.
