I always thought (and part of me still does) that until you have physical (or downloadable) proof in your hands that you're really, truly a published author, you can only do so much promoting. What are you going to tell everyone?
Hey! I wrote a book!
That's great, and a significant accomplish, but look at those bookstore shelves, or around your library. Tons of people have and they're actually published. You have the proof right there in front of you to read or skip as you would.
So what can I do to get my name out pre-published?
Talk about it, of course, and I do several times a week on this blog. Got the site up and running, and every so often I add to that, too. What else? Hmm, I'm a member of RWA. Don't have that PRO pin (the one that says they recognize the fact I finished a story) mostly because I never bothered to get it. OK, that's my fault.
What else? I'll have to think about it so I can do it. But it's hard when you don't have the proof in your hands to wave around and scream about.
