Hey Ian,
I also experienced the same problem with the daily notifications coming in seemingly hourly, it seems to have been related to the pinned posts which we have since removed. Apologies for that, as with the uptake of any new platform there are going to be some teething issues.
I hope though that you do continue to persist with the new format of ANZSTAT as your (and many others) contributions have been very valuable to me personally, and likely most other people on the list. As I mentioned to John Maindonald in his thread, any feedback that you and others are able to provide in the early stages will help us improve the experience for everyone.
Personally, I hope that the discussion forum becomes as frequently used, if not more so, than the old mailing list, becoming a useful and more easily accessible resource. I imagine there were many useful email threads I missed out on that occurred before I subscribed to the mailing list.
Ben
