I've been using the TinyMCEcomment plugin for quite some time. It has been working great and looks even better on my blog with self-made theme.
However, the only problem is that whenever somebody submitted a comment, new paragraphs (hitting Enter once and not Shift + Enter) in the comment become line breaks instead. Also, lists become line breaks as well.
Any help would be greatly appreciated. My blog is at http://www.khairul-syahir.com, if that would help.
