Posting in your G+ community for school

Sharing content to a community is much like sharing to one of your circles or even in your public feed. While you can post to your respective community directly from the community's page, you can also post from basically anywhere on the platform. You only need to find and click on the following, to display the extended post creation tool:

Users will see their own profile picture and name.

Extended post creation tool.

Each post may contain: 

1.  A relative short text description, type your text where it indicates "What do you want to share?". Try to keep the post short, to avoid forcing the reader to scroll down.
2. Some images from uploaded files or images already in your GPhoto collection. The new version of Gplus allows you to publish several images inside the same post.  
3. A link to an external website. Even inside private communities, users will be redirected to external websites without a warning. 
4. A short multiple choice poll.
5. A shared location. 

Once you created your content, please remember to verify all of the following security settings. First click on the "post visibility restriction link" (pointed with a green arrow)

Secondly, select the community to which you are posting or change the domain visibility option. For this example, the post about to be shared will be visible only by "Aulas Digitales de Secundaria" and restricted to Goethemail.net users.

At this time, Google+ prohibits you from sharing to multiple communities. Also, when you do choose to post to a community, you will not be able to share that same post through the public feed — meaning you'd have to post your content twice for it to show up in the community and in the public feed. If you do post your content to a public community, though, it will still be visible to users who navigate to your profile page. But if you share a post to a private community page, it cannot be publicly viewed anywhere except in that community.
