Okay, thanks to Emily I should be up and running with two Twitter accounts:
One is for Mark R. Hunter the writer (that's the penname I'll have on Storm Chaser, as confirmed by Whiskey Creek Press). This will be all about writing in general. It'll be called, yep, MarkRHunter
The second is for Storm chaser specifically, and is called stormchaserbook:
I did wonder if I could keep a twitter about one specific novel going, but I think there'll be enough periodic news to go around. Since I'm new to Twitter, be gentle with me! I have no idea what I'm doing.
