Yes. Writing help would help. With how bad my grammar and spelling was back is 2000, I still don't get how I got As in creative writing class, and even an A++++ once. My senior project was a Hyper Text (which is pretty much the same as Hyper Card and kinda like the PowerPoint for mac but a lot cooler. which is saying a lot from a PC fan.) Choose Your Own Adventure. It was fun ass hell to write. And there was also a poem section separate from the story. And even with my bad Grammar, which I did edit it like 100 times but I am sure it still had grammar issues, I had got a A++++ on it.
But yes... so... bad grammar and bad at getting what is in my head to paper. This means help with writing is always loved. We can talk on skype at any time, and all the writers we end up with could have meetups at some point. And Skype can do multi people chats so that is a cool way for all the writers to chat together.
as for voice, I have an issue with it too. I hate how you sound different to yourself then you really sound. I have a hard time doing a low voice, I tend to not talk load enough when I do. and my normal and high voice sounds a hell lot younger then it seems to to me. but, that is kinda why I changed the ages of characters. even a "young sounding" 15 year old would be okay I believe for this project.
