The Classroom Wall is the place where Progress advocates can post information about topics that OpenEdge Classroom Group members may find interesting and relevant to their progression as OpenEdge Developers.
The Wall is divided into sections, with each section introducing a related topic and having postings on the Wall as sub-pages within that section. Take a look at the Table of Contents in the right-hand margin - expand each section to see the relevant postings.
If you are a new developer then a good place to start is to access the Getting Started Tutorials.
Then browse through the following sections at your own pace, learning as you go. Bookmark pages of interest and keep coming back to view the latest postings on the Classroom Wall.
