Community portal is more of a holdover from the Monaco skin and before. I agree that Community corner is mostly worthless, but if you want to notify users, you need to edit it.

You can edit MediaWiki:Communitymessages-notice-msg to edit the message box that pops up after you edit MediaWiki:Community-corner.
