Admin button on the server screen?
 

Don't know if this is new or just never noticed it before. With 0.7.0, on the Server select screen in the upper right hand corner is an 'Admin' button. Being the curious "What does this do?" type, i pushed it and the whole screen went dark and had to cold boot hehe.

Is this just something that showed up using an emulator or is it a feature of it?

While it may do something for SOE admins on eqlive, it doesn't do anything for us here. The only reason it's there is because your client will show server population numbers if it was tricked into thinking that you're a loginserver admin, so the emu login server always tells the client you're a loginserver admin.
