Hi all! can any one tell me what is the best method to run openser out of all the methods mentioned in the link below? http://openser.org/install.php Thank you, Regards, Padmaja ----- Original Message ----- From: &lt;users-request(a)openser.org&gt; To: &lt;users(a)openser.org&gt; Sent: Wednesday, May 31, 2006 12:09 PM Subject: Users Digest, Vol 12, Issue 83 > Send Users mailing list submissions to > users(a)openser.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://openser.org/cgi-bin/mailman/listinfo/users > or, via email, send a message with subject or body 'help' to > users-request(a)openser.org > > You can reach the person managing the list at > users-owner(a)openser.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Users digest..." > > > Today's Topics: > > 1.
