Late to the party, and cannot create an Intrepid account

Hello there all, little late to this train it seems! that said, tried creating an account on the Intrepid site so I could prepurchase the game, and it won’t allow me to create an account, problem with my username it seems… I have a request into support, is it possible they just have it shut down now to new purchases?

I have also never been able to create an account, never got any help for it either.
