I suggest changing either the "Painting" or "Conversion" fora to a mixed forum of either "Painting/Modelling" or "Conversion/Modelling".

The reason I suggest this is that there's not a clear place for posts pertaining to modelling to go. I've had my modelling idea posts given "This is not the place for this kind of topic" no matter where I seem to put them.

I'd prefer to see the painting forum converted over in this way, since it a) sees more traffic, and seems to me to be more closely linked to the modelling than conversion.
