I was terrified when I posted my first chapter. I had no idea how to do it, and I only had Wordpad... so no actual word processor. It ended up being one big block of text, but readers didn't seem to mind. I learned a lot fast, and am still learning.
I have so much stuff partly written as well... so many docs just sitting there, including a rather well thought out sci fi that will probably never see the light of day. I was letting writing take up too much of my life, and I have learned there are times my brain and fingers need a break.
