Have a read of this threadglen. The OP has links to the Secret Santa FAQs and if you read the last half dozen or so posts, you'll see the latest timescales.
Got our back as always cozie, thank you! Any questions about the Secret Santa can be sent to email@example.com, we are very happy to help. The spreadsheet shenanigans are going well and donors should hear news about their match by the beginning of December.
That's right, Ken. There will be quite a lot to do - not just matching (athough that will be a task and six in itself) but back-of-house stuff like assigning alternative names and sorting the emails and labels (if we're going to get label templates again this year.)
I wouldn't worry. I know people are anxious to have packets on their way but I've sent parcels off only several days prior to Xmas before now (scoring 0 for organisation) and had them arrive on time within the UK.
