I inquired about a license that fit a small company like mine and was told that Alfresco is targeted for the large enterprise and that the Community Edition is made available for the purposes I was looking for.
So how does updating of the community version work? I have on good faith contributed to the open source community by diagnosing and reporting the large UIDVALIDITY IMAP problem to both zimbra an alfresco. The zimbra web client now accepts a larger UIDVALIDITY and I tried the new zimbra release and the 3.3g alfresco release and I get a different error. I find my original UIDVALIDITY post in the alfresco tracking system and not only is it fixed, but other related problems, including the new one I ran across, have also been fixed.
I have worked with a lot of open source products, but this is the first one I have seen that actually took an issue from the open source community, and NOT provided the resolution back to the community. I really don't understand why enterprise customers are benefiting from my efforts, when I am not allowed to.
