Like I all ready thought, it still doesn't work even after more than 48 hours. So I think something is wrong here.
Site details:
username: msiteur
requested url: http://msiteur.heliohost.org
I've the same problem, signed up yesterday at 17:30 (according to the email) but I still can't reach my account. Maybe I'm to early, and is my account up within a next 24 hours, but I think it's quite strange. My site is msiteur.heliohost.org
