The college newspaper is a good place to hone your writing skills, but it may not be the only media option on your campus. A college may feature many different student-run media ventures that publish a newsletter or a magazine. A student group may put out a magazine that focuses on the underground music scene, or a newsletter that is devoted to pop philosophy. You might even consider creating your own publication, recruiting a volunteer staff and working with the college on publishing and promoting it.
Volunteer work is a good extracurricular option that will also look good on resumes. For example, you can sign up for an "alternative spring break" program where you help rebuild homes or tutor at-risk students instead of partying during spring break. You can do regular volunteer work through the school year. Even a couple hours per week could make a big difference to the local community. You might consider starting your own volunteer effort and recruiting other students to help out.
If you're a political person, most campuses feature student organizations such as College Democrats or College Republicans, or whatever party with which you are affiliated. These groups can help coordinate grassroots efforts to get out the vote for a political candidate or provide support in other ways.
Most campuses feature clubs that focus on various cultures. For example, St. Norbert's College has a French club that seeks to promote and increase awareness of the French culture, as well as a Japan club and Spanish club with similar focuses. Student organizations like this often sponsor festivals, concerts and discussions to promote these cultures, inviting students to participate.
