|
|
* Detailed instructions how to use this plugin can be found at

|
* https://github.com/friendica/friendica/wiki/How-to:-Friendica%E2%80%99s-Facebook-connector
|
|
*
|
|
* Vidoes and embeds will not be posted if there is no other content. Links
|
|
* and images will be converted to a format suitable for the Facebook API and
|
|
* long posts truncated - with a link to view the full post.
|
|
*
|
|
* Facebook contacts will not be able to view private photos, as they are not able to
|
|
* authenticate to your site to establish identity. We will address this
|
|
* in a future release.
