True, a newspaper is about current events, but that's not all it includes. Perhaps your readers want their opinions expressed or to hear someone speak out about what they'd like changed in their school. In that case, publish some letters to the editor and write some editorials of your own. The paper does represent the staff, too, not just the student body. Write features that focus on the school, or debate an issue that are not just random topics selected by the sole vote of the editor.
Deadlines are important.
News stories lose their relevance fast and if that paper isn't published in time, the readers lose their interest in its topics and the whole issue is void of purpose. No one will bother to read it or care about what it might say. Each writer on the staff is a contributor, therefore they need to contribute to the paper. Let everyone write an article about something necessary to put in the issue, and then let them write something else that they'd like to have printed, if possible. You might be surprised at what is produced, and many of those free-choice articles may end up being ones you strongly desire to publish.
