@chinesegeorge: you are right, I have been travelling lately so my overview of the headlines was somewhat lagging... done now. Yes, we would like to keep the headlines in a way that presents a good experience for the reader, so outright ads, asking questions and generally posts with no informative content do not belong there. I don't however, mind a producer or professional modeler writing a story about his/her work or achievements - it is a blogging environment and as long as what you do is blog to your readership, you should be fine.
In this way, the headlines are NOT like a discussion forum, but rather like a co-created publication. The Groups area is for discussions without restrictions to the post format.
@craigindaytona - I believe that headlines should not be reserved only for completed builds - there's a value to welcome all your ideas there, unless, as mentioned, they represent a good storytelling and contribute to the readers' experience. That said, obviously presentation of a completed build falls into this category 🙂
