I am starting a new blog that will hold continual contests that last three weeks. When one contest is over, the next one will start.
I'd like to be able to have a message at the top of every page that says something like, "The current contest theme is ______. It will end on _______"
I know I can change it in the header.php or sidebar.php each time, but I was wondering if there is a plugin that I can install that will give me a "message field" that I can write in each time. Any ideas?
