That's too bad that she's thinking about joining, but isn't joining

Maybe she's just taking a much-needed break. But, I think it's wonderful that you have the privilege/benefit of being able to talk to Suzanne directly, and I'm glad she's offering you some valuable advice behind the scenes. And the FB group has caregivers and advisers familiar with ProZinc, too.
While you think the posts here might be "more about chatter," I think if you look more closely, you'll see that the posts are often friendly, yes--many of us have gotten to know one another over time--but our interactions also offer suggestions and much needed emotional support--this disease can be lonely and stressful for those of us struggling to help our kitties, and it's beneficial to have the support of like-minded people. Sometimes that support doesn't just mean posting just about questions or problems.
Have you thought about contacting some of the people from the ProZinc board and inviting them over here? The messaging apparatus on the original board works if a person has their in-board messages going to their email account. Many of us on the Lantus board have worked behind the scenes to keep in contact with one another after the board went down, and thankfully one of the members took it upon himself to create this back-up board that we really appreciate because we, like you, see the value of net-working with other caregivers and experts. Thankfully, some of the advisers from the original board have joined us to offer advice, and we appreciate that more than they could possibly imagine.
I hope you're able to get Corky down from those highs you're so worried about soon!
