Roberto, I'm not sure if you're replaying to my post or the orignal one. I know how to get ACS from sourceforge. I was asking about (upcoming) 4.1 which Don has said is hosted on OpenACS.org. I was curious also because as far as I know 4.1 doesn't exists yet.
The fact that for the whole time OpenACS.org is up there was no information anywhere about how to get the code directly from CVS is another matter.
And for those who still wonder: to get 3.2.4 directly from CVS:
cvs -d:pserver:anonymous@cvs.acs-pg.sourceforge.net:/cvsroot/acs-pg login
cvs -d:pserver:anonymous@cvs.acs-pg.sourceforge.net:/cvsroot/acs-pg co acs-pg
