<human>: Around Christmas 2009 my wife was talking to her cousin and they were saying how much they had to lose weight and thought it would be fun and motivating to have a competition and see who could lose the most by the middle of the year. I overheard the conversation and having recently started teaching myself web development I suggested I would create a website for them where they could enter their weights and see a graph of who is winning...

I started building it and realised I may as well make it so anyone can login and do the same thing. I checked to see if ourbiggestloser.com was available and surprisingly it was..

Fast forward to the middle of 2010 and my wife and I had both lost more than 10Kgs which was pretty much all we needed to lose and several of the other family and friends that joined us did well too.

My wife and I put on about 20Kgs since then so of course we are competing again and to be honest she's kinda kicking my arse at the moment! 

But since that time there hasn't been a huge amount of groups competing on the site until New Years Resolutions 2012 and now there are more active groups competing on the site than ever before which is brilliant! I know it's fun and motivating and I get a kick out of people using something that I built.

There are about 11 active groups at the moment. It would be great if more people joined in but I wouldn't suggest all the /loseit people join one group because that probably wouldn't work so well! But if we can think of some ways to segregate and create some groups it would be great to not only compete within our groups but against other groups to see who can lose the most weight...

I'll leave it up to you guys to figure out how this would work, if anyone is interested of course, and I look forward to more people using my site.

Can you condense the text into a few key points?
<bot>: Created a website at  for people that want to compete with family/friends or complete strangers to lose the most weight by a given end date. GL HF! :)
