I joined some groups and in some of them(and also in my overview ),
appears the information that certain member of that group has a new song, photo or video. How can i give this same information of my new media uploaded, to the groups?
Yeah, they get, but this one is already done. Just complicated .
1. Become a member of a group. Seems like you know, how to.
2. Go to "Show & Discuss".
3. Choose the media you'd like to add (you can also choose them from your profile)
4. Besides the links "Write a comment", "Forward to friends" and other stuff, there is an option: "Add to group". Click it. There will be a list of every group you joined (or founded).
By the way, you know that you can add media withing your messages with this text-editor, don't you? Makes pretty much sense, especially in the groups.
