Good, but could be better

Hi, i really like how it looks like on my site, but i’m afraid of the long term commitment with you guys, i’m starting my site and i expect lots of comments, i don’t wanna have to replace it with something else and lose all my comments.. is there a way to have it all on my site? not just an iframe?

Also, would it be possible to remove the branding off of the system if not have it all on my site? because the branding is just, not suitable.

Hit me back, thanks.
