For anyone that doesn't know about it yet a fan site has been setup to facilitate finding matches, playing tournaments and chatting with other players.
The website is http://www.lawandchaos.co.uk
The web based client is http://client.lawandchaos.co.uk
There are a number of different tournaments running at any one time including all game types and once a month there's a chance to play against Julian in the Gollop Wallop.
The client is constantly evolving and there are some great things in the pipeline for the future.
If you've not tried it yet take a look, there's nearly always people online looking for a game, either friendly or tournament.
