Hi! I'm relatively new here, too. Most days I just don't feel up to starting my own thread -- there's something intimidating about it, even though I know there shouldn't be. But I like responding to other threads! It wakes me up, keeps me vigilant, reminds me that I have a fellowship/chevra, and often inspires me. You've just inspired me -- THANKS!
You might also try finding a couple regular writers whose writing "clicks" in your head, and send them a personal message to ask how they got started. Just being here is a great first step -- KEEP COMING BACK!
