winSPWW2 comes with a range of pre-made campaigns and scenarios. There is also a scenario editor that enables players to create their own scenarios.
The game's battle generator (pictured here) can be used to create random battles from most of the campaigns during the Second World War. I have compiled a list of suggested random battles on my SPWW2 random battles page.
There is a forum for winSPWW2 at Shrapnel Games. It can be used to discuss the game, find opponents and obtain technical support.
