I don't know of everyone else has had it but I just received an email and survey from Health Unlocked about some sort of launch and publicity campaign starting in a couple of weeks' time.
I'm afraid it will be goodbye from me if there is any linkage to Facebook, Twitter or similar. For reasons partly to do with privacy and partly to do with lack of synergy, I left the atrial fibrillation group on Facebook.
The message that came from Health Unlocked about what's ahead didn't explain much, so a I may be worrying about nothing. I'm quite happy with things the way they are.
