Wiki deletions

[Bert Freudenberg]

Those following the changes on wiki.laptop.org will have noticed that  
someone (probably some bot) is deleting parts of pages - noticable by  
deleting "+", and everything starting from the first "&":

	http://wiki.laptop.org/index.php? 
title=Forth_Lesson_3&diff=prev&oldid=42243

People are reverting these changes mostly, but there are pages  
slipping through, and it is annoying.

A simple way to prevent this would be to require log-in for  
deletions. Could that be enforced?
