Maybe it's because we have no answers, Merklova. I realize English is not your first language, but your comments verge on insinuations of other forum members not caring and deliberately withholding information. You may want to tone down your rhetoric, because it's going to get you into trouble. The administrators here are not "all knowing" - we help where we can. We also realize that there is published material out there that we don't know. We can only share what we know, or what we have theorized (and need to be clear about the differences) and the other forum members can only share what they know. This is one of the most caring forums I've been on - and I've been on quite a few.
