I'm going to get it out of the way and admit I work for Harper Collins and InkPop.com. It's a little shameless approaching people on forums trying to encourage writers to try out a new site, but I want you all to know my intentions are completely genuine. You can completely ignore me and I won't think of any of you any less, but I'd like to just let u know about this site.
I'm approaching you all specifically because teen fiction lit is a big part of the community at InkPop and I think you'd all really like it. If you really take your writing seriously, I really encourage you all to submit your writing samples to the contests. The cool part? Harper Collins editors actually read your work and you could get published.
If you're interested or have any questions, hit me up. I'm around.
