That is a shame @welshblue
Maybe you would be interested in joining our forum and Facebook membership. Your work would have a large exposure, you would also be the first Paint.net artist invited.
I know the other users would enjoy your work as much as myself and my associate have. No doubt it would garner more respect - by this I mean an example above; the hack of your excellently made spark plug and boxes, it's liked by someone who didn't like the original ? Totally disrespectful. Another example is your very clever screw tutorial. An Administrator who should be encouraging more tutorials like that in a raster image editor to improve the experience, likes a spin off image made from your work, but not the tutorial that allowed it to happen. Strange indeed.
