BuddyPress.org

Hi,
I need a plugin or modify the code to:
– Share an external content (from the other site) in my BuddyPress (Similarly the share facebook). So, have a button to insert external sites to share content on my site BuddyPress.

Alternatively, I would like to know, how to create a page with only the form “status update”
and stream without a header.

Thanks in advance. See you soon and good day!
