I have just registered to a blogging community with the specific demographic of teen bloggers. Run by a 17 year old, she hopes to give people new blogs to read within our own age group.
This community is called Teenage Blogger Central.
In order to have your blog part of the community, you need to register, and add one of the buttons to your page.
I'll be using this one
So if you wanna discover new blogs and simultaneously advertise your own, I think I just found you a place!
