Airtime and nin entered as a team. They may continue as a team or as individuals.
It is in my opinion not a good idea to enter a contest as a team. The downloads section in particular only associates ONE name (not two) for a park. This is the way the boards are written - using member numbers. So in team entries one member always plays a phantom role.
Also in my opinion, it may be harder to maintain a single vision and consistency with a team entry. While it seems that a team has the ability for one member to compensate for the weaknesses of the other and thus increase likelihood of a "better" park, this is not always the case. With more than one vision and direction, a design can be diluted and not as sharp. It can become a "camel".

A team can indeed create a superior product by combining forces, but there is no guarantee the team can multiply strengths and uplift weaknesses rather than just have a blander, more compromised product. Teamwork can be difficult and that is one of the benefits of having clubs where teamwork as a skill can be honed.
I have seen many great team parks. I have seen as many not so great team parks. There is never a guarantee a team park will be better
simply because it is a team park.
