I did send you two PM:s, one of them was the idea for assignment 28. So far there's no problem. My problem is that I didn't receive any reply - it seems to have got lost on its way to my inbox. I did check my profile settings and as far as I can see there is no setting that should prevent me from receiving PM:s. I have sent you another PM just for testing, please reply to it and make sure everything looks OK when you send it.
