I’m working on setting up a new discourse instance and found that I can’t use the same username @larry that I’m using on Meta even if I try to register with the same email.
The username reservation isn’t quite “released” to the public yet - you need to enable enforce_global_nicknames and fill in a discourse_org_access_key, which are not being given out yet.
Basically, this means it won’t work on sites that aren’t partnered with the Discourse team.
Right. My inability to create a username on my discourse installation was my own problem - I bootstrapped a new docker container but forgot that the postgresql database was stored outside the container, so my user already existed. Apologies for the confusion!
