Replying to comments doesn’t work

Hi All,

I have been trying to activate a “reply to comment” type plugin. I’ve done about 4 of these including “Better Comments” and “@ reply”. None of them have worked.

All I want to achieve is an option for me (as an admin only) to reply to people leaving posts on my blogs, and possibly highlight in a different colour.

Any help would be appreciated!

Thanks
