That might be a good idea. We're going to be in Disney then have a crazy week when we get back (Nutcracker Market, what!?) so I'm going to be swamped right around the time we matched last year.
I might play this year. We're less broke. I could run a Canada-only one for MMM and possibly other boards too, if there isn't an easy way to restrict matches by country? eta: or we can just encourage people to shop at well.ca and amazon.ca and not worry about international shipping.
I only had one request to not be matched with a Canadian/international nestie last year so it's not something that is a big issue. Don't let that hold you back!
