Seeing shots of IL-2, Strike Fighters and Battlefield 2 in the "Freeware Screenshots" section is a tad strange, don't you think?
So why not creating a screenshot forum for "Other Games & Sims", in which everyone can post their screenies from IL-2, X-Plane, Orbiter or whatever they like to play?
It would certainly keep the "Freeware Screenshots" forum for MS products (FS,CFS) clean and encourage others a bit to post shots of their achievements or moments in their favourite games.
If there can't be a whole new forum, then just add a "Screenshots,too" to the "Computer Games and Software" forum and let everyone put a "[Screenies]" in their thread title to indicate that this thread is about screenies.
