osseo What permissions should I set the new "acm" folder? 755? Thanks.
It is solely at your discretion whether you wish to set the permissions to chmod 777 or 755 or 644 etc. as there are several factors to be taken into consideration such as security vulnerability, permission access levels and others
To know in depth about file permissions and thereafter choosing the appropriate file permissions, Would suggest to google keywords such as "file permissions chmod explained" "file permissions unwritable" or "file permissions writable" which would result in ample search strings
