I really need to be put in Talybont because I just got a new job which is only within walking distance of Gabalfa, not Cathays or Penylan. However whether I get my message today, Thursday or in September doesn't make that much difference. It's nothing to stress about.
It's like you stressed all the way up to Results Day, and then went home and stressed about the next thing you could find. There was no publicised day for getting your allocation and you haven't been missed out.
