Houston, You have to understand that it is not a personal issue with you, why I deleted that posting. KS sent me few emails asking me to remove that posting saying it was posted wiithout any permission. Personally, I think that if an article is out there in the internet, then there is no problem posting it here. A link to the source would be nice. Having said that, if an author does not feel comfortable about their article posted in sajha, I have no problem in deleting such postings. It might seem personal, but let me reassure you that is not the case in any way. I hope you will continue to share interesting information and participate in sajha. Best wishes, San
