BTW, regarding tiger369: People don't like questions asked at different places in parallel, because they answer your question in their free time for free. That time may very well be waste if you already got the information somewhere else. If you want to reach different people, at least cross link your questions. ("I have have also asked this at StackExchange). If you just want to test if people at different place give you the same answer, then go waste someone else's time.
Surely though it is advisable to ask and get answers from as many places as possible to gauge a full and correct answer - I think it is very weird to have one forum constraining questioners to asking in that forum only - very bad science.
