Hint on setup wizard that the choosen profile name will block that name for groups
I am administrator of a locally focused Mobilizon instance: https://events.graz.social
Currently the discoverability between Events created as a profile or as a group differs harshly, but this is not clear to users (e.g., only groups can be followed, events from profiles will not get listed on federated Mobilizon instances and maybe more even I don't know of).
That's why we decided to enable that only Groups can create Events. Since then I received the same complain for literally every new user we got. People don't understand that the initial profile they must create is just an identity which can be used to create and perfom actions within a group. Also people to not understand the concept of groups and different profile identities at that point. As most of them don't want to create another personal account somewhere they already use the profile field for creating an identity for their events. Later they realize that they blocked their preferred identity for the group forever.
Advanced hint messages within the setup wizard could maybe help.
