For the English folks
The Facebook group is an Dutch only community. Not to exclude people who read, write and speak English, but just because there is already a great community in English: the MayDecemberSociety, of which I also am a member and administrator of. If you can read and write in Dutch it is not a problem, you can still become a member of the Leeftijdsverschil.nl Facebook group even though you are not a native Dutchie. But it is exceptionally Dutch in order to support people who are not so familiar with English.
