Would seem to be a bit paranoid. After all, unless you want to trademark the concept of 2 pixel = 1 foot raster drawings nobody can stop you drawing.
I'm not terribly worried about this; my concern is primarily with protecting our own drawings done under the Shipbucket label/style/scale via the correct Creative Commons license. Ships we draw are content created by members of this community and thus each one should be protected under a license (even a CC one).
We obviously came first to form the Shipbucket moniker but even the pioneers like MConrads were building on work done previously, in particular those RN drawings done over a decade ago by Unknown. All those surviving artworks now exist in the SB archive, I notice they have SB scale bars and titles (but not the copyright mark at the bottom), I can't remember if they always had that template or where pasted onto them when archived? If the former, then we owe the origins of the template to somebody else.
MConrads created the template (I have the original .PSD files he made, with guide ruler demarcation etc). The later revised templates started including the watermark at the bottom right. Those were created by our forum staff back in 2012 I believe. The "template" belongs entirely to Shipbucket.
The "Unknown" drawings were put into the MConrads template back when the Shipbucket photobucket account existed. They are NOT in Shipbucket scale as far as I can remember, but rather slightly larger (indicating to me a metric scale vs. our imperial one).
There are cases where that doesn't apply as certain drawings have parts that are all drawn by the artist who made the drawing. A good example is FD Scale drawings of ground vehicles such as armor, trucks, cars, buses and trains whose parts cannot be found in part sheets as parts for those kinds of drawings usually vary from vehicle to vehicle.
This will only apply in a few cases. We need to select a license that will apply to every single drawing, so the provision that some drawings will include parts drawn by the community as a whole must be incorporated. Also, I am primarily interested in protecting our Shipbucket scale work. The FD Scale work will fall in line behind our Shipbucket drawings based on whatever license we select.
