I don't know multi-users support in the way of identifiers are planned, but there are a few I could use for my script, as posted in the other forum.

$osuser - login name of operating system user, with properties of

.homedir
.appdir
.description
.group -
.privledge
.mircaccess - this is if user can read as well as write to mIRC home dir

$userdatadir - directory where user specific mIRC application data is.

$permsn - the read/write permissions of a file

The idea is, to have the script as administrator, as read only, and all the keys and settings files will be private and user

I'd also like to see the following command:

/chnpermsn - changes permissions of a file
