We don't care about your personal info. Maybe the Mediawiki software cares about your personal info? If so, that'd be on them.
Any edits you make to any page on this site will be publicly visible forever in the edit history. Don't make edits containing info you don't want publicly visible forever.
"Anonymous" editing makes your IP public and is therefore less anonymous than creating an account and logging in... which might be a problem if we allowed it in the first place. Which we don't.
