Yep, I know I said I was leaving. As you can all see, I have had objections to what @Scardoc has been saying in this thread and have voiced them. Scardoc has answered my questions satisfactorily. Everyone has a right to express their own opinions, surely that's what a forum is all about. This thread was started in the 'Soapbox - Have your say' section, so that isn't that at least a hint that it may be controversial? Whilst I agree with the comments of several of you regarding Scardoc's views, I do not agree that the thread should be closed. We've had a discussion , that's all and the majority of people seem to be 'against' the OP. If the OP wants the thread left open, I really don't see a problem with that. Please don't turn this into a forum where we are not allowed to speak other than to pat each other on the back and say 'Good morning'. What purpose would that serve? We need healthy debates. Yep leaving again now.
