Ask Nicola
I now run Ask Nicola as a standalone blog. That's the place to ask questions, serious or not, personal or book-related. You can read right here, but to comment you'll have to go to the blog.
Gemaecca
This is an experimental blog, all about my novel-in-progress, which is a huge historical novel set in 7th century Britain. If you like the idea of watching over my shoulder while I write, this is the place for you.
Mailing List
I also run a Yahoo list. There are about 250 of us. We talk about all sorts of stuff. Over the years it's become a cool little community. If you want to chat with like-minded people (and occasional contrarians) come and join us.
