I have to admit, I did "lurk" around for a bit before I registered.
I had seen so many other sites that were absolutely disgusting. There were sites where people posted something funny/harmless/asking for advice and it was ripped to shreds by the "diet police".
Some were highly competative and even gave advice on laxatives and the best way to make yourself sick and anyone daring to admit to falling off the diet wagon was practically disowned.
So, I lurked about for a bit before deciding this was a really good forum and registered. It's been brilliant and I think the support is fab - even when I have a bad week, someone helps you get back up again.
