[Mediawiki-l] Changing the Edit Page disclaimer...

[Matt McGhie]

Apologies if this is a simple change, but I can't I need to switch this text out on the 'Edit Page.'  --

***Please note that all contributions to MyWiki may be edited, altered, or removed by other contributors. If you do not want your writing to be edited mercilessly, then do not submit it here.

Where/how do I do this?  

Thanks,
