That's all fine, but a few problems.
1. So far we have one person who wants on
2. We have a ping list, but what's it for? Articles about teens spending too much time on the computer? Articles about teens playing with guns? You have to have a purpose
If it is something you really want to do, here are a few pointers (IOW, this is how I created the Mom/Dad ping lists):
Post a thread similar to what you have here in News/Activism. Networking with conservatives of a specific age group is certainly activism, so you won't (or shouldn't) get any crap from the "Wrong forum" nuts. You're a lot more likely to get attention in News.
Second, flesh out why it is that you're interested in having a ping. Will you be starting a weekly age-based, common interest thread? Will the ping be used specifically for pinging to relevant articles? List, for yourself, why you would want to have this ping; share that list with others, see if they're interested. You might not want to even worry about a ping list just yet. Maybe just run a thread like this in News, asking certain-aged FReepers to share their experiences as young conservatives. There are a whole lotta ways for people to be politically involved and active, regardless of their age, and some folks may be involved in things that others simply are not aware of. Pardon my syntax, just got back from Niagara (oy!)
Whatever you decide to do, have fun with it. Best of luck!
