There are a few ways to modify the layout and positioning of the Comments box. Not everything is possible, but there is a decent amount of flexibility. Can you post the URL of a K2 article on your site so we can understand what you're looking for a bit more? Also, please let us know what version of JFBConnect you're using.
Additionally, please post from the account you subscribed to JFBConnect from. Priority support is for subscribers only.
Thanks,
Alex
