Unable?
Andrew and I are seeing the Canada trip as backpacking for OAP's so we don't want to take much in the line of electronic equipment with us. We plan to travel with phones only and no laptops - BUT Wix (the provider of this excellent (until now) website and blog isn't supported for making updates from smart phones.
So, to keep in touch I'll email everyone who asks to be kept up to date and for everyone else there is always Fb.
