This could indeed be a useful supplement to our distribution address but only if the most needed informations are given. Mind that many problems are based on the problem of locations and often in situations at the border of two European countries.
These necessary informations for all of us could be: forum name/clear name/country/town/species ready for distribution, approx. number/personal collection only or readiness for shipping, too
An example: Peter Finke/Peter Finke/Germany/Bielefeld/P. paludicola, ca. 20/ready for shipping. (This is not an actual offer, but an example only).
All other things could be disputed about in personal communication.
To illustrate the point with a special request: I know of a young Swiss friend who is unable to get Paros in Switzerland at present. But living near the German border he would be ready to fetch his fish personally if the breeder lives not to far away. Otherwise he would be ready to pay a good transport company.
