Mother's new email address

We're either at home or visiting my sister and brother in law in Vancouver, or someplace that's home and then again not. Mother is sitting propped up on pillows on our sofa, but it's in a sun room which we don't have and I don't believe my sister and brother in law have either. Mother looks very much as she did when we last saw her in palliative care, and is talking in the same happy easygoing way. She tells us she won't be able to come visit again—she's too tired for another trip like that. We ask if she has an email address. She says "That's right, you can stay in touch by email."
