is it possible to allow only few special users to read bug notes? like for example when developers use mantis as exchange platform so there is no need for reporter to see these comment. currently there's only the option for public or private note.
That is supposed to be what the private note is for. Only developers and above can see them ($g_private_bugnote_threshold). If it's not working, please file a bug report.
ok... very nice :-) didn't think of it in this way. selecting specific user would be fine but is not a must-have. things work fine for me the way you suggested it.
