please use the original version from ms or other open source apps like fire - everyone pretending anythings else from that is simply lying. noone on this earth needs macmessenger with no real new features (besides it's a damn slow real basic app) and without video support - no video support? - why not use the original micro$oft app then? answer the question for urself. we all seem to hate bill but is macmessenger the solution... NOPE!
