I'm baffled people think it's ok to edit another person's personal profile, or maybe I'm misunderstanding things and miss the point or purpose of community profiles. Aren't they supposed to be personal? What is their point?
I think you are confused.
The Community Profile is not the same as the Personal Profile. Two completely different things, two completely different purposes and functions.
Your Personal Profile cannot be edited by anyone but you. It is used only on the forums.
Your Community Profile can be edited like all entries on the website, and it meant to link usernames to hacks/translations that they have released. It also links a user to their website if they have one, or to a translation group if they are in one. It is used in the database.
