That's because your logged into the manage page, log out and you will see it.

how do I allow someone else to access the backend of the server?can't seem to find where to give permissions.the permissions tabs just shows who currently has permissions for the server which at the moment is only me.thanks.

I had problems with mine but here is what i was told to do by Ausgamers staff.

To grant another user the ability to modify and control your Game Server
Rental server in GameCreate the person that you would like to add must
have an AusGamers account, and if it is a new account they must have
followed the steps required to activate the account.

You need to add permissions at two levels: permissions to control the
game and permissions to control the server.

To add permissions to control the game:

Go to YOURDOMAIN.ausgamers.au.gamecreate.com/admin/BrowseByGame.aspx and
click on the game under 'installed games'.
Near the top of the page there are some tabs (the 'Overview' tab will be
selected by default) - click on the 'Permissions' tab.
At the bottom of the Game Permissions page there will be two additional
tabs: 'servers' and 'configuration'. Select the 'configuration' tab.
Select 'get by email address', type in the email address of the new user
and click search.
Highlight the user and select the level of access you want the account
to have, and click 'Done' to save the changes.

To add permissions to control the server: Return to the 'Overview' tab
for the game by clicking on it at the top of the page or by going to
YOURDOMAIN.ausgamers.au.gamecreate.com/admin/BrowseByGame.aspx and
clicking on the game under 'installed games'.
Click on the server name in the list of servers for that game.
Near the top of the page there are some tabs (the 'Overview' tab will be
selected by default) - click on the 'Permissions' tab.
Select 'get by email address', type in the email address of the new user
and click search.
Highlight the user and select the level of access you want the account
to have, and click 'Done' to save the changes.
The user should now be able to login to your GameCreate domain using
their AusGamers username and password.

But clicking on that gave an error so i had ausgamers add my users.

you can also use their gamecreate page ausgamers.au.gamecreate.com just login with your details.

Yea, I won't lie...

I dont get the two tabs as per 'At the bottom of the Game Permissions page there will be two additional
tabs: 'servers' and 'configuration'. Select the 'configuration' tab.'

Also, sorry for the semi necro

I get neither, just the same screen.

So I'm going to go out on a limb and say that it's a job for support :(
