I sent a PM to Sea Grant and asked about the registration problem. They have answered back and said that it should now be up and running which would allow new members to register. It was explained to me that the site has an older version of software and they had disabled it to keep the spammers at bay while they upgraded their software to a more anti spammer fore mat. The upgrade is taking longer than was anticipated and is not yet ready to use. I have not checked myself but would imagine that you can now register using the old system.
