Decide on an issue that would be interesting to your target audience? What is your issue?
My issue is "CAREBEARS: NEED HELP NOW-FOR YOUNG PEOPLE ARE YOU HAVING A CRISIS? CAN'T COPE WITH LIFE? WANT SOMEONE TO TALK TO FOR SUPPORT? WHEN LIFE GETS TOUGH CAREBEARS IS THERE 24-hours a day!!!"
Carebears is for any young person in distress. You can emergency email, or contact our toll free number. We are there to listen and give you the space that could help you find a way through. Our counselors dont judge and we are available 24 hours day and night.
Is this on right track target audience is 13-16 years?
To help you define your "issue" you need to consider that the hot-line is obviously the solution to a problem. It sounds like you need to define exactly what is the problem. What is the real issue? Is the issue that teenagers are experiencing different crises, that they feel they have no one to talk to about their problems, or, is the issue that they simply are not talking about their problems at all?
Once you determine the bottom-line issue, consider a few more points of feedback.
First, while this is an age-appropriate idea, I think you might be limiting yourself in using only a the 3 year age span (13-16). Consider that in the United States legal system, 17 years old is still considered a minor. Also, consider that there is not much difference in the "issues" experienced by high school and middle school students. Why not make it 10-17 years old?
Second, perhaps define "crisis" more specifically. Is this a depression hot-line? A drug-related hot-line? A teen-pregnancy, abuse, or suicide hot-line? Or is it a hot-line that covers all of these things? If so, it might help to include this list in your explanation.
Finally, consider your contact options. Most of my students do not have email. They would use a social network (Facebook, Twitter) before email. Also, most of my students text message more often than making phone calls. Both of these adjustments would make this more "age-appropriate" in my opinion.
