You need to apply to group called AMEN Ikariam:
1. Register to forum then apply to group AMEN ikariam by clicking Groups button (below main banner). Find AMEN Ikariam group and click Join group. You will have to be confirmed member of Alliance in Ikariam to be accepted into this group. So when joining group if you dont have the same nick as it is in Ikariam you should contact mcgslo ingame or forum and let me know what nick you use in Ikariam.
Or simply register with same nick as in Ikariam.
