Hello.
I want to use K2 component and comment the K2 contetnt in my Kunena forum. Kunena specialist told me:

Kunena Discuss only works with Joomla articles; it does not with K2 things. Please talk to the K2 developers to ask them whether they're interesting in developing a plugin that will work with the Kunena forum component.

www.kunena.org/forum/9-Extensions-Modules-and-Plugins/136079-kunena-discuss-and-k2#172702

Anybody help me, how can i do it?

Now i am using "kunena discuss plugin" for comment standart joomla com_content. This is very comfortably.
