Hi Viv,
There are 2 new reports on your site. Look under Hidden / Reports and see if they are of any use.
I've also fixed the duplicates bug in the newsletter. 'Prevent repeat sends' now does what it says.
The newsletter report also registers any link a newsletter reader clicks - Not just survey responses as before.
And.. I don't think you've used the tokens yet. Try them out to add a bit of personalisation to your newsletters (is your name at the top of this ?)
