If I remember correctly, sometime back couple of people complained that their articles appeared / published on SSWUG.ORG web site without their knowledge and permissions.
Today, I was shocked and surprised to see couple of my articles (which were written on blog) appeared on this site. I don't remember that they have ever taken my permissions to publish at their site.
Following is the link of few articles published on their web site:
Simulating 11g Snapshot Standby Database feature on Oracle 10g?
Change behavior of GROUP BY clause in 10g
I don't mind publishing my articles on their web site if they would have taken my permission.
