You would need to call back a taglist (which from your blocks should be all the usernames), then you can check the newly entered username against the existing list of usernames, and notify the new user that their chosen username is already in use, and to try another.
Sorry I am a beginner.
Do you mean the block "call Firebase DB1.GetTagList"? But it doesn't have any extension to it so I can put block into it.
And does that mean I should create a list?
Thanks a lot! That's very helpful. Thank you for the help.
