Welcome to Connect Extension. This is the main page that is viewable by anyone. To create posts, add content, or access groups - you will need to register.
If you want to post content for anyone to see, this is the place to do it. The calendar on this main page is the next generation of eXtension's "Learn" system. There are a number of options for posting - including blogs, calendar events, and more.
If you want to get more specific and post to only a certain audience - try visiting the groups page. Once you click on groups in the main navigation, you can choose the group you would like to participate in. When you post content within that group, only that specific group can see it.
