    "abstract": "Recently Liu, Long, Tong and Li [Phys. Rev. A 65, 022304 (2002)] have\nproposed a scheme for superdense coding between multiparties. This scheme seems\nto be highly asymmetric in the sense that only one sender effectively exploits\nentanglement. We show that this scheme can be modified in order to allow more\nsenders to benefit of the entanglement enhanced information transmission.",
