Invitation to audiojungle "experiment"

in lack of an actual contact email, I try my luck here. Some weeks ago I received an invitation to take part in some kind of “experiment” as an author in audiojungle. The “experiment” wasn`t further explained. The provided link in this email, pointing to “”, resulted in an error page (ERR_NAME_NOT_RESOLVED).
Today I received a reminder for the “experiment”, either no success with the link.
Can anybody of audiojungle answer to this?
Thank you in advance.
