Dear all, I'm tagging you in this PR because you are listed as being an administrator of one or more repositories in the ACCESS-Community-Hub organisation and Github does not provide any better way of contacting people. At the end of this month ACCESS-NRI will be enforcing new policies regarding the repositories in this organisation. You can read all the details here. One important change that I want to draw your attention to is this one:

• No special access is granted at the organisation level to members. This means that organisation members:
  • cannot write to repositories unless they have been granted explicit write access at the repository level or are part of a team that has such permissions
  • cannot read private repositories unless they have been granted explicit read access at the repository level or are part of a team that has such permissions.

This means that your collaborators will lose write access to any repositories that they are not direct members when this change is implemented. Therefore, I recommend you check that every person that needs write access is a direct member of the repository and, if they are not, please add them.

Let me know if you have any questions.
