Nailsbro, I agree with Kalakisthan. I assume that we are capable enough to filter what is essential for us and what is not. Therefore, in any public forum like Sajha, there are always useful and not necessarily useful stuff, therefore, one has to be selective enough to use what is needed and to discard and ignore what is not. That is why we are in Sajha. To raise any hypothetical negative view, it will not help you out. If you truely have genuine questions, definitely in Sajha someone might give you a satisfying solution to it, not necessarily 100% precise, if your answer is not forumlated or readymade already? Because you will never be satisfied with any answer unless it matches with your readymade one. Do you follow me? I cannot gurantee that I would be able to answer your question, neither I have to, but for sure, I have observed many friend who have good analytical view. Just give try friend.
