Ok if I remember correctly, you need to use your email address or user name
not the display name. OC works on legacy style names, not the new display
names. So if your name is say Athaliah Opus or say John Resident you would
put that name, in instead of say Anastasia Marie Romanov. But you also have
to create a Google account for it to register your name I believe. What is
occurring is you are missing a step or doing a step in the registration
wrong. It has nothing to do with the collar its self if you are having a
problem with registering with the web interface. I suggest you go back and
fallow the steps again, but since your using the Opencollar Google group it
means you have some kind of account. so just slow down and try again.
