I was reading the Concept 2 UK forum in the CTC thread and Empty the tanks team were name checked - hey people we are famous!!
If you want to communicate with other Empty the tanks team mates you can do it on the Concept 2 UK 'teams and Clubs' forum. I have started a thread called 'Empty the tanks open to new members'. To contribute to the site you just need to register with the Concept 2 UK site.
