I always hit "new posts" and scroll through to see whats been happening. If people are asking for help and advice and none has been given I will try to help, but if there have been replies which are similar to ones I would have given, then I keep my gob shut (not like me lol).
However, I do agree with KD that those who stick to their "own" threads/diets are really missing out on a lot of support and information.
I don't tend to post much, but do read avidly especially those peeps I have met, and if I can offer any help or whatever, then I stick my twopennarth worth in. xxx
