You cant move players to spectators using amx_teammenu
Moving a player kills that player.
No support for both anonymous and not anonymous (at the same time) chat for csay tsay and so on.. In AMX you can do amx_csay amx_csayy amx_tsay amx_tsayy which the y in the end makes the message annonymous.
I know you can change it with a setting but this is annoying..
