How to cancel a tourn. i created

I just created a tourn and accidentally hit the mouse pad. i wasnt finished. this one is important to me as its in memory of my mother....no one has entered yet

Probably a bit late - if it is a club tournamnet, go to the club tournament page - against the open tournament you will see 'admin' link. Click on this and then you see a large button saying 'remove tournament'....
