there is a relatively new German online repository for physically handicapped refugees who require special auxiliary means: ww.facebook.com/ability4refugees
The aim of the group Ability4Refugees is to offer an exchange platform for aids needed by refugees with handicap. Supporters are the "Andreas-Mohn-Stiftung" (andreas-mohn-stiftung.de/) and the "Interessenvertretung Selbstbestimmt Leben in Deutschland e.V. - ISL", a human rights focused Disabled Persons Organization (DPO) (isl-ev.de/).
Thank you Jan for your post and your support to the Wefugee community.
