Hi everyone,
Is there anyone out there who know of a php and mysql news system like the one they use on this web sites:
http://www.sublimefootball.com/

With category/sub categories, related news articles, etc.

Anyone who can help me?

You'll probably find quite a few on http://www.hotscripts.com or you could write one to do exactly what you need. CuteNews has plenty of features, but i personally pefer doing my own. Everyone's different though.
