It is not the intention to become more like Facebook I can assure you Des. A lot of good info is shared on CBF (unlike FB) and we have been looking for a way that members can show appreciation for a tip, piece of info, joke etc without having to post.
I agree the thumbs down was a disaster - I got quite a few and you wonder what you have to do or how much of your life you have to give to stop people being such a negative, born to take and give nothing bunch of anonymous cyberbullying heroes. People who meet you in real life and wouldn't say boo to a goose. Although in truth doing that is largely pointless.
