Hello Danubius :) Congratulations for these clubs. Really nice and easy way to be linked to other collectors around the world.
I would like to suggest an idea for the Souvenirsheet club: for example, for me, to have 5 repeated souvenir sheets is not an easy job :) They are no like stamps. I know other members have more repeated sheets than I do anyway. So, my idea is ... why dont you create two platforms?? this one, instead of souvenirsheets would be 5souvenirsheets, and you make another one as for example, 2 souvenir sheets ??
maybe this would allow other people to exchange, and you leave the option to keep on 5 souvenir sheets to ones who want to keep 5 per exchange
what do you think ??
this is just a positive comment, ok ??
thanks
