Registration Instructions for Subscribers to GWIC 3G Science Case Team Working Groups

How to Register for the GWIC 3G SCT Working Groups

Anyone may join the GWIC 3G Science Case Team Collaboration, however, joining in itself does not provide access to anything. The Collaboration consists of members of the the GWIC 3G Science Team, which is a closed group, and members of various working groups, which are open. Below, we outline the steps for joining the Collaboration.

N.B.If you are already a member of the GWIC 3G Science Case Team or have already joined some GWIC 3G SCT working groups, then you are already a member of this collaboration and do not have to join again! Collaboration members can jump immediately to the section below entitled "How to Join the GWIC 3G SCT Working Groups".


  1. Go to Select 'GWIC 3G SCT Working Group Enrollment'. You will be prompted to login. There are a variety of login options. If you are a member of LIGO/VIRGO or KAGRA, you can login by selecting the apprpriate icon.

    Alternatively, you may be able to use your university, college or lab login id (if it seems strange to you to login to a service at using your username and password from your university, click here for more information on how and why we do that). To see the full list of places whose login IDs we accept, click on the "Allow me to pick from a list" link

To join a working group, simply follow the steps below:

  1. Begin by going to the list of groups for GWIC 3G SCT Collaboration here. The page should look like this:

    You will see a number of working groups to join. You will also see other groups which are marked "Closed". These are groups for administration or other purposes. Working groups are all marked as "Open", meaning you can join them.
  2. To join a working group, all you need to do is check the "Member" box.

    There is also an "Owner" box. You will not be able to check those. When a box is checked, you are automatically subscribed to the mailing list for the working group.
