Nostalrius Begins - Quality wow vanilla realm (1.12)

Heyo,
wanted to start playing on the server, but sadly it wont let me..

If i try to register ( https://en.nostalrius.org/register ) i fill in the required fields, check the captcha and agree to the Terms of Use, it pretty much just reloads the site, no confirmation or anything.. If i try to login in WoW it says unable to connect, and if i try to login on the website it also just reloads the site and nothing happens..

Is something broken atm? or is it just me..?

Hope you can help me,
Xilef

Idk, I just registered in the site and it works. The problem is, you can choose a name with 20 characters on the site and to login on the game there's only 16 max...
