UK Accountability Buddies,

This is not just for people from the UK but due to time zones it would be preferred.
I've tried too many times before and lost a little but then fell off the horse and had to start from scratch. This is part of the reason I would like to add more friends and have some sort of accountabilty or reason to keep up with it. Im about 238lbs(17st) and need to get to about 196lbs (14st). Thats about 185 of my total body weight. Thats a big margin. Im gonna break it down into 5% chunks and see how I make it. Would love the help and encouragement from other people.
