[Mediawiki-l] Wiki vandalized

[Cyril Pavillard]

Hello,

I hope this is the right place to request some support for this subject.

Our wiki (http://www.wikimac.fr) has been vandalized and even though  
I found some informations on the mediawiki site, I can't really  
figure out how to resolve quickly this problem and how to protect our  
wiki to avoid such a problem again.

1) Is there any quick way to recover the pages that have been erase  
without having to go on the history and recover the content article  
after article ?

2) I guess to avoid this problem, the best way would be to move our  
wiki to version 1.5, is that right and is there some extra things to  
do on the default install to protect it ?

3) Is there a place where I can post (if this can help) the IP that  
vandalized our wiki ?

Thank you for your precious help

Cyril
