Re: [Mediawiki-l] contents of page disappearing

I run a mediawiki site for a small group of users. I recognize that my question is very basic, unfortunately I couldn't find an answer to it. I noticed that when two users (or probably more) edit the same page at the same time, the entire contents of the page are totally erased when the user who last tries to save his/her changes clicks on "save page". Although I can bring back one of the previous versions, this seems to be a major problem, and I always assumed that mediawiki had a clever way to deal with this (sending a warning to one of the users, for example). What shall I do? Is there something I can change in some file(s)? Thank you in advance for your help. ________________________________________________________ Luis Borda de Agua 2502 Plant Biology Building University of Georgia Athens GA 30602 USA Phone: (706) 583-0943 Fax: (706) 542-1805 _______________________________________________ MediaWiki-l mailing list MediaWiki-l(a)Wikimedia.org http://mail.wikipedia.org/mailman/listinfo/mediawiki-l
