They did not post a link or anything but found it while cruising for new updates in case they figured it out.
May work for some but Step 4 may still not work for others such as me. There is no "register" only log-in for me and if you're still experiencing this I'd suggest submitting ticket so they can address the issue quicker.
Edit - just copied the exact URL from the step 4 guide and this allowed me to register a new account but took off the Aeria linked URL causing them to not sync together and still unsuccessful.
Which I'm curious whether or not it's worth spending my AP on a current realm/channel if we're going to be getting Aeria designated servers to ourselves or new ones in general. No point spending on an old realm if there is a new one coming
