Version: (using Devel) Installed from: Compiled sources I am using Kopete 0.5.80 (kde 4.0.81) with an MSN account. I was suprised that I could not set myself to Invisible using the Status button in the contact list toolbar. I had to choose Edit statuses and add the status myself to be able to set myself to invisible.
I think this was fixed in revision 819704 by uwolfer, should be available in KDE 4.1 Beta2 and later. http://websvn.kde.org/?view=rev&revision=819704
