I recommend that NOT try to improve nicosdirectory.
sp_directory IS improved version of nicosdirecory.
Nicosdirectory doesn't support spam-protected emails,
which sp_directory supports.

I changed nicosdirectory into sp_directory and a little
bit fixed sp_directory.

Please start from sp_directory.
