Few things to make contributing News easier:
if you save this now it will show up under its respective category however, you can set a few further things by scrolling down the page:
URL path settings: this will set a readable URL for your page. It would be good to follow the already established patterns:
e.g. news/committees/im_exec/notes/2007_08_05 (for IMExec meeting notes). This helps if you want to link from a different page to this, but has no real effect on where the page is and can be changed any time again.
Comment settings: you can turn off the ability to leave comments to this page.
Menu settings: don't set anything for the menu, unless you really need to start a new menu item
File attachement: well, you can attach a file here
Authoring Information: you can change the author here if you are posting for somebody else
Publishing Options: set here 'Promote to front page' if you think that this news bit should show up on the home page, the default is not to show it because the front page can get pretty cluttered, but important news certainly should show there.
