I would gladly contribute some topics/findings to a lightgun forum, it would really help weed through the clutter. Especially as much like a racing cab, desiring lightguns can dramatically change the design/software setup of your cabinet. Some of the info regarding crt lightguns is old but still entirely usable - I'd be willing to contribute info about using Wingun for instance.
Would also give a good area for my TopGunCon project that I want to finalize and share with people (using crt guncon2's in Windows xp, 7 and up using the TopGun driver, my flasher software, and a small hardware circuit.) I'd like to see that arcade IR sensor gun project and the usb2gun topics put there too, that's fascinating info for lightgun players.
