As long as you are logging in as a registered user with admin rights, it should work.
FYI: Super admin rights are not necessary to assign AO AV (I just tested this on my server.

)
AH! I missed one thing. The channel has to be
moderated in order to give yourself those rights, which makes sence if ya think about it. Only moderated channels need to be assigned an Operator and only admins and operators assigned to that channel can allow/disallow others to Voice, Auto-Voice, or Auto-Op.
To see what I'm talking about, edit the default channel or create a new channel and put a check next to
Moderated. Switch to that channel and right-click on your nic and the options will be available.
SUGGESTION: Create a new user account with SuperAdmin and Admin rights and use THAT account for your TSClient sessions. I've accidently killed my admin status before, and if I didn't have the Admin account as my backdoor, I would have had to redo the database from scratch.
