Here are a few things to keep in mind for the chat:
1. Make sure to mark all your questions and comments with #VAapp. You can address them to @richellemead, but without the hash tag, no one else will be able to find them and read them.
2. If you've been to my past chats, you know I'm never able to answer everyone's questions. Things get crazy! So, if I don't answer yours, please don't be offended! I'll type as fast as I can. Follow the hash tag because if something is asked multiple times, I'll only answer it once. You might find your question was already answered. I also tend not to answer things that give away big book secrets ("Will so-and-so get together?"). :) And sometimes, questions start flooding in so rapidly that I unfortunately lose some of them.
3. If my answers are short, don't be offended either! Remember Twitter is only 140 characters (less with the hash tag). So, I'll have to keep it brief or possibly refer you to my website or FAQ, if there's an answer there.
4. The chat is to celebrate the app, but you can ask other things. If you do have app questions, though, this is a great time to ask because Penguin people will be around and tweeting to help with those.
UPDATED: @PenguinTeen will be around to answer a lot of app questions and also to give away three ARCs of The Golden Lily! They'll explain how to win when the time comes, and it's an international contest.
Also, remember: Click and follow along with hash tag #VAapp. Otherwise, you may not see my comments and other people's questions. Also mark your own tweets with #VAapp.
