RC1 is available on the first mirrors (I know, only "inofficial"), but Help seems to be not available.
I pressed "F1" in a WRITER cocument of my "LibreOffice 3.3.0 RC1 - WIN XP DE [OOO330m17 (build 126.96.36.199)]" and got message "Error 404" for link
I sent an email to webmaster firstname.lastname@example.org
We are announcing a RC without existing Help? That seems to be a ticklish issue.
But because it seems to be intended, not a bug.
