MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg11344.html
) which is awfully slow. In case this is of use for anyone else, I attached a modified version using 'join' that runs much faster, only has some compatibility issues with Mac.
