You can use this function to post articles which you would like to share with the community Choose a title, then enter the text of your article. If appropriate, add a pdf, image or video: you have created your article.
You can opt to post this article to a group to which you belong. In this case, this content will supplement those already present in the group. This step is optional, however: if you do not attach the article to a group, it will nevertheless in the Publications tab on your profile page.
Media
You would like to share a photo, computer graphic, video or document with the community? This is the function to use. Like for the articles, you can choose whether or not to attach this publication in a group.
Use the button Publish in the community also to create working groups or themed groups. These are useful for organising your publications and reserving them for chosen members, if appropriate.
