I've had a flurry of requests lately from groups who would like to do a "virtual" author visit. Usually we do this by webcam, using Skype or Gmail. But my local library has nice videoconference facilities, so sometimes we're able to connect that way as well.
It's easier than you might think, and it's a great way to get to know each other when I can't get on an airplane and fly across the country. If you've never considered the possibility of a virtual author visit, feel free to check out the information on my website here.
