Registration Problems

I just got this message on YouTube and thought someone here could assist.

hi amaury
i’m sorry to bother you here, i’d liked to have written you on forums.ffshrine.org, but exactly here lies the problem: i cannot seem to register with the site. all works fine with the registration page itself, i check agreement of terms and try to register, all that happens then is that i land back on the index page, with no further comment.
trying to log in results in a message that i tried to log in with a wrong user name or pw.
i’d expect a verification mail to be sent to me, i checked, also my spam, nothing there – and it wasn’t announced anyway. all that happens is – back to index page w/o comment.
i’d really like to register, but this is frankly annoying. i also didn’t find any contact-offer, hence i write here.
i’d be obliged if you could help me or forward this message to someone responsible.
thank you,
