feat: create post and comments in anonymous groups #63
Description
Upon creating a group, I should have the possibility to create an anonymous group whose membership is requirement is the ownership of email address of a given domain.
Indeed upon registration, the user will provide an email (that needs to be verified with a confirmation email link). So we can use it as a filter to create semaphore groups (like in yeap)
That group would be a semaphore group.
All users already registered on the forum whose address match the requirement would be automatically added to the group when the group is created.
To create their first post in that group, users will need to generate a semaphore proof client side (use e.g timestampt+groupId as scope).
For simplicity the server will generate that proof once. After this check, the user is allowed to post anonymously in the group.
