I've been updating the WRITERS PAGE on my website, and came across a few new links I think would be particularly helpful to anyone submitting novels or short stories, or for that matter pretty much anything. I published quite a few short stories and other short pieces on my way to getting my first novel published, and I highly recommend it as a way to hone your craft and to get some positive energy to keep you writing!
There's a more exhaustive list on the site, but these are some new ones I've come across:
Top Five Cover Letter Errors - brought to you by the folks at Prairie Schooner and phrased contemplating submissions to literary magazines, but their suggestions would apply to pretty much any submission
QueryTracker, an online agent database I offer with the caveat that I don't actually know how accurate it is, but I've heard from others that it's great
Good luck with your writing! - Meg
