I think that's quite likely, bonniebeth. Heather said (about a year ago now!) she had requested Geobra's help, then sent the whole database to one of their staff to look at. So I don't think its Geobra silencing the database, zugpferdchen.
I like the links to Geobra's pdf files on PlaymoDB (they are, after all, only hyperlinks!) and my initial suggestion that this might have been done by Geobra (with Heather's permission) was a completely serious one. Perhaps Geobra are also adding new sets? I don't know how it works, but I wouldn't think new sets' pdf links or inventories could be added automatically, could they?
My biggest fears are that the older sets (no pdfs) will be overlooked from now on, new parts will not be given names, counts of parts will not be added and the errors in the database will not be addressed. It will quickly lose even more of its former value. I for one would like to see someone back at the helm.
