I know this is late and y'all moved the conversation elsewhere. But I just wanted to drop my two cents on. You should never be afraid to write with people who are "better than you." Writing with people who were better than me is part of how I learned to be a better writer myself, by putting myself in that position, I picked things up. Granted, that may not work for everybody. But that's how I got from a one line poster to where I am today. I too was afraid to write with the "good writers" and didn't until I could at least string together several sentences (they wouldn't have let me anyway). So I think that fear is within all of us, but we shouldn't give into it, especially if said writer wants to write with you.
