literacy organizations or reading/writing volunteering

Just writing this post up in the hopes that some of you have been involved in literacy organizations or something similar. I've always wanted to get involved in volunteering activity that relates to reading/writing. Only thing is, not many of the literacy programs around here seem to want teenagers around.

It doesn't have to be a literacy program exactly, but some sort of volunteering experience/organization that deals a lot with writing and reading?

I'm thinking I may have to start something of my own if I come across another things that says "You must be 18!" :)

But I'd love to hear about your experiences!
