Hi! I've added to MediaWiki a feature which could be an alternative to page protection: the verify feature. I've added to the sysops' bar a 'verify'/'unverify' button: 'verify' sets the current revision as 'verified'. When there is a 'verified' revision, users can still edit the page, but new revisions are not shown until a sysops verifies it again (of course, even new revisions can be accessed though the history, and the verified one, if any, is in bold). 'Unverify', of course, removes the protection.
I think this would be a very good alternative to page protection against vandals. I would like to heard what do you think of it.
Regards, Salvatore
