Allow vanilla members to comment on posts in a WordPress blog
I have configured a Vanilla install to handle Facebook, Twitter and Google sign in. It works great.
The Vanilla install is now going to be embedded in a WordPress blog using 'Embed Vanilla'.
How can i have my Vanilla members to comment on the WP blog without having to login/enter mail in comment field and still offer Facebook and Twitter sign in?
