I'd certainly contribute if I had the equipment, which is really what I lack and which is well out of the pricerange of a nutjob on SSI >:P
My expertise is more in the realm of hardsubs than anything really important to OT. (That said, I crudely hacked an almost-OTV ANH out of EditDroid's version that had the 1985 mix and isoscore + the ITV audio. It's been making the rounds, apparently. And I did try to make a stereo version of the 1.0 mix. It was a disaster, but I tried :(, it would have been nice had it worked better.)
