Hi Moritz,
I understand what you are asking for and from what I can see, it would seem that splitting the sub-forum Physical Models and raising it up one level to become a full forum might take care of that issue. Then we would have a separate forum for Physical Models and the child boards within would have the same rank/status/level as the other forums that were in the Current Builds sub-forum.
Not sure if we really want to do that but maybe putting it to a vote to see how the others feel about it and we can go with the majority decision.
Other options:
1. Leave it all in one forum but promote the child boards to the same status as Physical Models, Profiles and Pixels, Stories, Aero-space. In the process it might be necessary to rename them to reflect the association with the original Physcial Models forum:
Physical Models - Sea
Physical Models - Land
Physical Models - Scifi and Fantasy
Physical Models - Other
To be honest, I am not keen on another change but it can be done.
2. Combine the child boards (Sea, Land, Scifi and Fantasy, Other) again under Physical Models (as it was previously before it was divided up).
