I'm being so sincere right now.

how to register ?

Just type login, then when it says username put anything, then the password is "portal" or "portals"
After that, I'd suggest typing Apply.
Then Continue. It tells you to memorize this long list of numbers but don't bother, every time it flashes off, a number or letter changes.
Then just continue

I spent ages exploring this a year or so ago
