I applied to Strathclyde first and Glasgow second, so had an email saying they had received my application on the 9th November like you did NittyNat.
I emailed them yesterday just to check whether it was 28 days from the 1st Dec as iLanny said it was for Edinburgh and they have just replied saying:
"It would normally be 28 days from the acknowledgment e-mail, we would advise you to check track and your e-mails regularly for any updates. A decision may also take longer due to the Christmas and New Year holidays."
So it might be next week - slight freak out!! OR it might be later.... not a huge amount of help but thought I would let you all know!
