It may be by design but why not restrict the same to the open sub-groups?? This inconsistent implementation acroos open and restricted groups is more the issue, IMHO.
I actually like the flexibility as in a family group I use my nickname, in the Ham group I use the call sign, in the business group I use my full name.? This saves creating a bunch of IO accounts and then juggling the logins.
