Thread:Support/About MediaWiki:Privatedomains-instructions/en (2)/reply

Example.(com|net|org) is the standard example URL, that's true. I believe that the idea for this extension came from a student of the Stanford University, hence why there are Stanford references in the message. Personally I don't have a strong opinion either way, but it's nice that there are two different domains in the message, to illustrate the fact that you can allow edits from multiple domains as opposed to just one (though, well, that should be obvious).

The "save" message is MediaWiki:Saveprefs, the same used on Special:Preferences. Changing that to the reference in the message is OK, it's just that there are 23 instances of the message (the English one + 22 translations) which need updating.
