One final note before you start developing the specifics of your program plan. When people hear you're doing something with Wikipedia and education, they'll approach you with their own ideas or views on how you should proceed or what you should do. Before you comment on their ideas, think:
Does this help me achieve my goals? Is this in my target audience?
If the answer is no, don't be tempted to take on their suggestion too! You and your program volunteers may have unlimited initiative, but you have limited capacity — be aware of your limited time and other resources to stay on track for success! Enacting the plan you've established for your first term is the most important thing for you to do. You can consider expanding your scope after you have a successful pilot, but stay focused on your specific goals for at least your first term.
Remember, it's always better to do a great job with a small pilot than to try to do too much at once and not achieve meaningful results on your education program's many facets! Keep it small, keep it defined, and stick to it!
