My friend and I wrote a post together and published it each one on our blog (both wp blog!).
I'm just asking if is possible to have some sort of comment exchange between the two blogs; meaning if a reader writes a comment on my friend blog about that post, automatically it appears also on my blog and vice-versa.
I have found pingpacks and trackback... but i didn't understand how they work and if allow "comment exchange".
Thankyou for your help
