Make a welcome page / block for new members
It'd be nice to have a special page or block for the group that serves as a "thanks for joining and welcome" message to new group members. Something that has to be clicked to dismiss/acknowledge for new members that join, and perhaps a way to redisplay it for existing members. But this content would NOT be accessible to non-members.
My specific use would be for special links for group members, like the invite link to our Discord server, or link to our 'code of conduct' page, etc.
