Hello Roberto,
hope you passed your midterms. In order to make the beta release more popular for testing we could announce it as a news and put your tarball for download on openacs.org as you suggested.
When will the new-file-storage tcl library be ready for testing... After Easter break [I will be snowboarding in the Austrian alps 😊] I will set up 3.2.5 on PostgreSQL RC3 (if nothing else will be out) on our new machine... I would like to test the new-file-storage to death, because we want to use it in our official launch (end of April).
Thanks
