A public full list of all writing instruments of individual collectors is rejected by the forum admin and the majority, because members appear largely anonymously and such a listing would have no practical use. Collectors also generally have only a part of their stock actually for sale, so a complete list would receive many enquiries without result. Instead the section Offer and the module MyPMS exist for internal communication; for sale and trade activities reference is made to separate platforms like morepens.de. Collection size alone is also not regarded as a quality feature.
