In this version of Chalab, you must create a separate account for Chalab and Codalab. If someone included you as part of a group using your email, you will automatically get a challenge template designed for that group when you login. If you are not getting the template that you expect, you can ask the group owner to add you to this group. Some templates are public and you can join the group to which they belong by changing "Actual group" in your Profile.
