Thanks everyone, we're approaching the 30 mark which is fantastic. I'll post page 1 of the spreadsheet (minus addresses) in a day or two. Make sure your name is on it and the number of swaps is correct. Thats probably the best way to shift the blame er.. I mean avoid any transcription errors.
I've got about half the addresses so far, don't all rush to send them at once (again, fear of transcription errors), but make sure they're through before the closing date.
One last thought, if any participants have already swapped a lot of beers with each other and would prefer to see what other brewers are getting up too, drop me a message. I can shake the magic-8 ball a second time if your names come up in a pairing.
