I am relatively new to this great site so my idea may have been tried a million times before but have you ever had a post where you can go off thread ? it would be interesting to start with a topic and see how and where it ended if folks didn't stick to topic, bit like when you're searching google for ' How to make a great G&T and end up with 'The execution of Saddam' that 6 degrees of separation theory.
I have looked at the 'Battle thread' but my tiny little brain doesn't get it! anyway just a thought.
Thank you again for a great site
