Sorry you got a somewhat curt response to your last question - it's one of the hazards of placing yourself on an open Site like this one - but I believe the adavantages of this Site far outweigh the disadvantages, so please don't be put off coming back. You will find Features about each Subject Section, which are changed every week, so if you check each Section and read the Features, and then ask any questions you may have, I'm sure you will find a breadth of knowledge that will assist you. Some opinons you receive may be a little more 'robust' than others, but it's all an exchange of ideas and information, so I'm sure you can enjoy asking, and answering questions here. As far as I know The Answerbank is unique in terms of its format, and the majority of visitors enjoy their experience - I'm sure you will too.
