Sorry - I still dare not try to write in german, but I do have some reflections on the discussion about "die Anfragenflut".
As far as I can see there is no real "homepage" to this forum where you are informed about the purpose of discussions and chats here (if there is one it is certainly not very obvious).
On such a page the introductory notes could inform "fortune seekers" that this forum is the wrong place, that such information is best found with renowned dealers and auction houses.
The first thread that now meets the eye is "Identifizierung und Wertbestimmung von Briefmarken Erkundigen Sie sich hier nach den ungefähren Handelswert von ..."
That is a bit ironic in perspective of what is being discussed right now.
As your discussions are running now, any beginner would hesitate to ask any questions for fear of being snubbed by the elite.
As for Dachbodenfunds: this is literally how I started my own collection. With a large bagful of Massenware, and more or less moldy and stained stuff found after +50 years in a family house. Going through it, not really looking for a fortune but scrutinizing cancellations and stamps and postcards (if they were readable att all) experimenting with paper qualities and colours, learning to read catalogues, searching for literature, has been an invaluable experience, and extremely fun even though 99% of the objects were useless in any serious collection. This is how I started my own collecting; I think I have moved from basics to a second or perhaps even a third level. And I would recommend anybody who has a boxful of "worthless stuff" to start there, that is a very inexpensive way to learn very much.
I am very sorry that I can not take part in this discussion in german.
But you should all know that I enjoy all discussions here, that I learn a lot from them
Thank you for your patience!
