Jetpack Add a new Service ?

Hi there,

That option only exists in WP-Admin, not in the WordPress.com sharing buttons interface.

Go to your WP-Admin area, and go to Settings ->Sharing. You should see the link to add your own button there.

If you don’t see it there, can you please give a link to your site?

THANK YOU VERY MUCH ??

Happy to help ??
