Bitt, I meant that I do not feel qualified to contribute to threads discussing say US politics or US health care or even many tech subjects for example, not knowing enough about the subject matter. I would not really feel comfortable making what could be seen as an irrelevant comment along the lines of 'this is how we do it over here', which although it may be of interest to some, others may see it as perhaps an arrogant attitude of 'so this is how it should be done'.

I try to follow the dictum:

"It is better to remain silent and be thought a fool than to speak out and remove all doubt"
