Trying to login to jforex for contest using Community nickname as login. Is this correct or am I missing something? Can you provide the proper way to login to jforex for contest?

The contest platform requires usage of a separate login/password. Those are different for every contest month and are sent to the email of the participant when be subscribes to every consecutive competition.

On its turn, the community login is permanent and can be used by the participant an unlimited period of time. This account is needed to subscribe to contests, take part in the social activity of the community etc.
