I've been trying to join the DSA Dolch Alternate Layouts Homing Keys GB for a while now to no avail. I kept getting an error that "Shipping Address1 is required" when attempting to check out.
I finally got around to emailing them and got a quick response that it's a known technical issue that they are working on, and for a quick resolution you can click on "My Account" at the top right after logging in and complete the "Contact Information" section of your account and try again.
This worked for me and I was able to join the GB.
Just wanted to pass this along in case anyone else was having the same issue as me.
