Start plastering this on everything ...
Didn't the recent letters to all U.S. congregations regarding JW.ORG signage at the local KH include the specifics of fonts and even the specific Pantone color to use? If one desired, one could make a very similar sign with:
JW
FACTS
.ORG
Plus, if this board is to be believed, the WTS lost its request to trademark "JW.ORG", so no pesky lawyers would bother you. A vehicle parked near the Assembly Hall would be noticed by almost every single JW driving by. At first they would squeal with delight and try to take a picture with their phone to post on FB or Instagram to show how well the new website's being advertised. It would take most people more than few seconds to realize the difference and understand the implication.
