Oh cool! I've been in the process of converting all the .mod's I have to .uge for some time, but it's been very slow going on my end, not as much time in my life as I thought I would have it seems.
I'm still working on getting all of this Volume 1 and Volume 2 converted to .uge, so those will (hopefully) eventually be available for purchase. In any case, I hope you find success in making those conversions for your projects!
