Spaces are shared accounts where users can publish problems, contest and manage members. You can organize spaces around competitions, problem archives, classes where you teach, etc.
Each space, gets its own address at eolymp.space domain. This address is generated randomly, but you can personalize it in the space settings.
Spaces can be public, meaning anonymous users will be able to view the space's site, published challenges, competitions, posts, etc. On the other hand, private spaces require the user to log in, when clicking on the link to the site of the space, the user will see the login form and only after logging in will be able to access the data of the space.
By default, an administrator must manually add users to a space, but you can also allow users to register in your space. To do this, go to the space settings page and enable the option "Participants can join the space themselves".

The user who created the space will automatically get owner's permissions. But you can additionally grant permissions to other users to manage your space.
