The other thing is that I've joined PopJam and they're going to give me a shout out this afternoon! If you're on PopJam, come find me at 'SarahMcIntyre'. And my co-author Philip Reeve joined just last night, so you can look out for him at 'Philip_Reeve'.
I found out about PopJam at Zoom Rockman's party from PopJam Content Producer Melisa Hasan ('melisa'), who encouraged me to join. And my first friends there were Zoom ('Zoom_Rockman') and Jamie Smart ('FindChaffy')! The app is free to download, and it's very creative and drawing-based. I haven't had a lot of time yet to explore it, but it seems really exciting. Also, PopJam has an 11pm bedtime, which is actually rather healthy.
