Huh? It uses PostgreSQL as its database. There are proprietary plugins if you need to use a commercial db instead, or you're free to write your own (though that's not an itch I'd expect to see scratched -- the PostgreSQL support is fine and presumably if you want an open groupware implementation you also want an open db behind it). There are proprietary plugins if you need MAPI Outlook support, just like there are proprietary plugins for Kolab if you need MAPI Outlook support. Other than that, I'm not aware of any functionality missing from the open product. Beyond that, I'd say OpenGroupware's far more open than Kolab in terms of not being tied to particular implementations of servers (OGo supports any IMAP, not just Cyrus like Kolab. OGo doesn't require any ftpd, unlike Kolab's ProFTPD requirement. OGo doesn't require any specific MTA, while Kolab is tied to Postfix. Some of those requirements with Kolab can be worked around, but some can't). It's also far more open in terms of being standards-compliant for addressing, calendaring, etc., rather than doing Kolab's ftp+IMAP folder combo that's highly non-standard and that almost no clients support. later, chris
