In the bp-share-it.php file you didn't register its function for the activity stream so there is no call to it in the admin option page. Only for BP Media did you call it but I don't use that plugin. I would like to use it on my activity stream because I have installed the Activity Plus plugin that allows to upload images, videos, and links. How can I call Pinterest to use in my activity stream?
Also, is it possible to add Instagram?
Thank you for this plugin!
