[arch-general] How can I post on bbs.archlinux.org?

Hello, I am sorry to write here about this about I would like to register on https://bbs.archlinux.org to have access to the Arch forum. The problem is that I am unable to install Arch but the registration page is asking me the result of an Arch command that I cannot run because I cannot install it in the first place. So I cannot register and I don't know who to contact to help me. Is someone here can help me with this situation? Thank you.
