Search on "Studio" worked for me: http://209.29.131.76/vbulletin/search.php?s=&action=showresults&searchid=1237725&sortby=lastpost&sortorder=descending
Several "Studio 9" threads. It really is a shame there seems to be no solution for the problem caused by massageplanet.netarians' love of acronyms too short to search on. Adding an asterisk to 3-letter ones [Pro* would get Pro, Prof., professional etc] used to work, but lately it seems not to. So all the S9 posts are buried. Try "mamasan" or "Maggie" maybe.

Perhaps you were expecting numerical order after the word "Studio" and stopped looking too soon [to your 'puter "9" comes after "873" and not before "11" even though"09" would, unless you take a fair bit of trouble to convince it otherwise].
