Hi @robinacue –
Sorry for the late response. I looked through the WP Repository for BuddyPress Social Media plugins and found only one – “BuddyPress Social” – which seems to do what you looking for. I installed it on a test site, but it didn’t seem to work very well (or at all) for me. Maybe you might have better luck (or more time to figure it out).
Maybe others on this forum might have some better suggestions.
Also, if you are just looking for social media icons just on the forum section of your site, you might look at “bbPress Social Network” https://wordpress.org/plugins/bbpress-social-network/screenshots/ – I haven’t used it, but it gets very good ratings.
