You will be able to find the organizations page as the last page in the left menu on the main page at https://hub.catenda.com/orgs

Here you will see an overview of all the organizations you are an owner of.
The organizations list is sorted in descending order by default but can be sorted in ascending order by clicking on Name at the top of the list.

Organization owners will be able to click on their organization to be taken to the Organization page of that organization.
