I have used JIRA before, I understand all of the limitations etc...no matter what letters, numbers, dashes / no dashes, combinations I've tired ...even different browsers I keep getting the same error message "you don't have permission to change the site name"
But I'm not changing the name ...I'm creating the first/ original name ...this is literally the second page after you create your password!
I've searched the boards but don't seem to see anyone else with this problem.
