You may be thinking about how some crowdfunding campaigns immediately ask for shipping addresses from everyone at the close of the funding.
That’s not the way Glowforge is doing it.
When they are ready to start the process of shipping your Glowforge, they send you an email to confirm you still want it. Then you fill out a form on the web site to provide your current shipping address.
So you haven’t been forgotten. All shipments so far have only been in the USA, and they are still processing orders from the first few days of the initial campaign.
