Thanks for running this.

Aside from logging on, I missed pretty much everything due to going to get a chinese takeaway meal for the family, consuming the food, then watching a classic film with one of my lads (Pulp Fiction).

Congratulations to Morgan (Stash author) for winning against a tough field.

Thanks to all who took an interest.

Thanks, Graham. Great tourny and a good scrap at the top for the overall first place.
