But, and I don't mean to troll or flame, just get my job done, it sounds like if I want MP on the production database, I should stick with the Red Hat this time around, eh? Hopefully I can get some infrastructure to test on sometime. It would be neat if MP on FreeBDS was very straightforward. It would be neater still if I could make some small contribution to everyone elses' efforts to make it happen. :) Thanks, -danny -- http://dannyman.toldme.com/
