Chang,

Thanks for the comments. The discussion forums on support.sas.com are, by design, a place where SAS customers and SAS staff can interact. Other threaded forums, such as the SAS-L mailing list, are traditionally used only by SAS customers without much direct involvement from SAS staff.

As a moderator for the EG discussion forum, I like to have the SAS customer participants communicate with each other. I typically will contribute only when a thread/question arises that I feel particularly well-suited to answer, thanks to my role in developing the product.

Another very prolific SAS contributor, Cynthia Zender, participates in many of the forums and spreads her wealth of SAS knowledge all over the place. I'm very pleased that SAS experts such as Cynthia have a place where they can contribute in a public way for all to benefit.

As far as editing postings -- it's true that you can edit your own postings, but you cannot edit postings by others. I think most folks consider it bad form to edit an existing posting in any substantive way.

As moderator, I can edit/remove postings in the EG forum. That's a privilege that I'm not sure that I've ever used. We welcome all feedback, positive and negative, and we appreciate the chance to respond with information and use the insight to shape future product releases.

Chris
