I've paid for quite a few shareware apps (Cliptrakker, PicView, Putty, WS_FTP Pro, EditPlus2, Mach5, Ad Aware, PSP) and mods (Full Canvas Jacket, Desert Combat, Battlefield Pirates). Free mods and apps are great, I'm all for them, but I'm actually happy to show my appreciation for the time and work put into these products.
In the case of Subsim's Bonus Mods like Pacific Aces and the SH2 Hi Res kit, they have been paying the server, contest, and general expenses this website runs for over 3 years. Without them, things around here would be very different. The costs of keeping a website like Subsim going are considerable. Thanks to all who have donated.
