I've downloaded and am finally building a couple of your lovely O scale freebies, and am trying to send you a small donation ($USD$10) but the donation site keeps making the credit card and address fields I have already filled in blank every time I update the amount. I'll try again using Paypal (which I hate, but if I have to use it, then I have to use it).
I'll send you some photos when done, although it will take a while - I fit my modelling in between work, although I do work from home, so the card kit(s) sit right beside my desk, which is a bit dangerous :-) I'm currently building the O-scale maintenance shed, which I'll try to fit on my micro layout (which already has your Quonset building on it)
