I am not sure if this point was raised in an issue already. We need to improve the tools for collaboring between organizers of a competition. Generally the interface is clumsy and the access permissions are not making it easy.
Current problems
1. Accessing task
You typically need to identify the name of the task and the number of the competition (in the URL), open the Resources menu, check for the tasks with the same name that are marked as "in use", and finally click on it to check if they are linked to the competition in question.
2. Task edition
Importantly, you may not have access to the task (and to edit it) if you are not the owner, but just a co-organizer.

3. Sharing server status information
This problem was solved by #2158
4. Adding collaborators (minor)
Original issue: #1807
a) In competition.yaml
It seems that we don't have a admins or organizers field in the file competition.yaml in order to easily add other users as organizers of the challenge.
b) From competition creation UI
When you create a competition using the UI, you can add admins from the interface but when you save the competition, the admins are not there. Updating the competition with the admins works.
5. Select task no convenient
Not directly related to collaboration, but the editor's interface is not convenient when selecting task(s) in "Edit Phase".
