# Group Services in the Brave New World¶

Welcome to the ACM group hosting infrastructure. This document assumes you are already familiar with its sibling, Navigating the ACM’s Services (sometimes also called README-BRAVE-NEW-WORLD).

The ACM offers JHU campus groups storage, web hosting, database hosting, mailing lists, and other services as needed.

Note

You should feel free to delete this document from your group directory when you feel sufficiently comfortable with the contents. It can always be found at /afs/acm.jhu.edu/readonly/group/admins.pub/README-BRAVE-NEW-WORLD-GROUP.

## AFS Groups¶

We will have created two AFS groups for your use:

org:$YOUR_GROUP_NAME_HERE-admins org:$YOUR_GROUP_NAME_HERE


The former can manage the latter (i.e. can add or remove users) and can also manage itself (isn’t that swell), so that as your membership and officers change you won’t ever have to send us email or anything! :)

pts adduser $USER_NAME_HERE org:$YOUR_GROUP_NAME_HERE


And to remove a user, say

pts removeuser $USER_NAME_HERE org:$YOUR_GROUP_NAME_HERE


Note that your users (or even admins!) do not have to have ACM accounts; you can use their JHED IDs just as well, by using $JHED_ID_HERE@win.ad.jhu.edu for the$USER_NAME_HERE part. (Though you will have to ask them to authenticate to the ACM systems at least once before our systems “believe” they exist; see Using JHED Identities with the ACM Systems in Navigating the ACM’s Services.)

Feel free to create additional groups as your access control needs dictate. We suggest that new groups be owned by your -admins group. The magical incantation to use is

## Mailing List(s)¶

We also offer mailing lists for group use. These are fully decoupled from AFS and so may be used independently – that is, you don’t have to have storage space with us to have a list, and vice versa.

List administration and archives may be accessed via the web at https://lists.acm.jhu.edu.
