Hi Everyone, Here are two documents to help in using the NSDL Communication Portal by THREDDS participants. The first is called, "Getting Started with the THREDDS Wiki", located at http://comm.nsdlib.org/docman2/ViewCategory.php?group_id=67&category_id= 64. The second is called, "How to Submit a Document to the THREDDS Workspace", located at http://comm.nsdlib.org/docman2/ViewCategory.php?group_id=67&category_id= 65. Since one can not currently submit a PowerPoint file, my suggestion is to print PowerPoint files as PDF files which can be submitted. I hope you'll find them useful for collaboration on THREDDS efforts. If you find either of them confusing please let me know, so I can correct them. Thanks, Chris
