Thank you all for feedback - very helpfull, especially links supplied by BaldFriede
I am glad that erroneous move of this topic provoqued active discussions of the structure of PA, which, I'm sure, will lead to better organisation of forums and subsequent expanditure of Archives in general
Would like to add that I fully agree with the contents of letter sent by Man Overboard to Maani, especially in the part relating to "Prog which is not in the PA yet". As I mentionned before, branding a band "Non-prog Music" in advance just because it is not yet in Archives for some reasons, is undercutting flood of information about it, and limiting chances for it to be ever included in PA
