On my todo list today is to get a post up to see if there's interest for a bracket tournament for the top 8 teams (which I should have done much earlier), and there will be dates for that.
When is Victoria Day? Because I'll just place the dates so it doesn't interfere, and as for the Quidditch-over-the-summer things... that I haven't thought about, though an international tournament could take place(?). The World Cup, it seems, is every 4th year, so that would have been in 2005, which leaves 2005 pretty open.
