The intended purpose of the mailing list is to provide the parents of a kindergarten group (Kindergarten "Die Wichtel" in Heidelberg Germany) an easy way to get in contact with everyone in the group and use it for child care questions and suggestons and organizing things. I was elected into the parent council of the group and then tasked with setting up a mailing list. I found that freelists.org would be a fitting service provider. My goal is to have a closed discussion space. All other providers I found so far are too much focused on commercial usage, we also don't want to push anyone to use any specific messaging app.
