A sports group of my local sports club unofficially uses a Whatsapp group. This group is used in particular for announcements (eg changed meeting place, etc.). At the moment I find it unrealistic to migrate all participants to another system. However, it might be conceivable, at least for announcements, to open a second channel so that those who cannot use Whatsapp are not completely excluded.
Is there any experience on this topic? Is there possibly a Whatsapp crosspost software to another channel?
