Where can I create an article?

Once you have joined and logged in, click on the My Folder link at the top of the page.  Since this folder belongs to you, you will find that you can edit it and add things to it.  To add an article, click on the add item tab and select article. Now you can give the article a title, a summary description, and  body text.  Click on Save to make sure all this gets saved in your folder.  You have just created an article.

If you are creating a lot of articles, or other content items, you might want to create some additional sub-folders within your folder to keep things organized.  All of these will belong to you.  And everything you publish will be kept somewhere inside of your folder.  More details are given in Guide to Authoring.
