Thread:Project:Support desk/Random - without link (novice)

MediaWiki - 1.16.5 PHP - 5.2.6-2ubuntu4.3 MySQL - 5.0.67-0ubuntu6

I've been given the task of creating the intranet page for my department where I work. I'm a complete novice with mediawiki and everything i've created so far has been based off other entries people have made on our intranet but with some slight modifications as i've been learning as i've been going along. Given that it's the companies intranet, I don't have much say in downloads of extensions or modifications to the wiki which may be required to do what i'm looking to - which isn't too bad as i've got another idea i know i can do instead but won't look as good.

What i'm hoping to achieve is; I'm looking to create a category full of pages with information about my department then, I've created a template with two page frames, I would like a random page from this category to appear on one of those frames - so that each time the page is loaded a different random page appears in the frame without the need for the user to select the random page link

Is this possible to do without any extensions or modification? If so can you walk me through all the steps? - each time i've tried to look at how to create a category i keep getting pages that just tell me it's possible, but not how to do it - also i'd need to know everything about making the random page appear without the link.

Thanks for any help.
