I often find myself astonished at looking at other people's freeware screenshots. I think it would be a good thing if admirers were put in the conditions of trying to make their FS look more like those wonderful screenshots.
So why not encourage posters to always specify what appears in the picture? What scenery package, what enhancements, what aircrafts, what addons... the ideal complement of this would be if every user specified his/her hardware configuration in the signature.
I understand sometimes this could be difficult, because often people don't remember exactly all that they installed, but still...
