thanks Rao for bringing this up. Actually our company has moved to openser around 6 months ago after reading the rumor spread around on the openser lists that SER is no longer being maintained. Looking now at the new SER I must confess that we are more than impressed about the new features and substantial changes to SER. It seems that, unlike openser, the guys behind SER spent the time not on cosmetic and superficial changes but on real improvements. I assume this difference in working style comes from the fact that openser is lead by a company that is capitalizing the open-source spirit to satisfy the day-to-day needs of it customers whereas SER is being maintained by guys who have a long term vision of things. While it will surely cost us some time and effort for us the decision is already clear that unless openser integrates the SER improvements we will go back to SER.<br><br>Bye<br><br>Kil Il<br><br><b><i>Rao Ramaratnamma
