KARLADAM  This is exactly how the PC client works as well due to public demand from users to clean up chat to remove the bots and spam that was in there, so now you need to prove you're a real person before you can enter the rooms.

What exactly is it about the PC client that you feel you are 2nd class for not having?

KARLADAM  What exactly is it that the PC Client does that you think you really need in the mac client? The vast majority of things the PC client does are simply not something that you'd want in a mac product. This is not a port, it has no intention of looking, or behaving like the windows client, it is Yahoo Messenger for the Mac. If there is real functionality that enriches your IM experience that we don't provide, do share what that is. If you want to use the Windows client that runs perfectly fine in VMWare or Parallels.
