Discussions in K2

The plugin Content works with K2 but is not possible to exclude or select categories. I have tested the exclusion of articles by ID, and it works with K2. Also I have noted the plugin creates the discussions with a page load of the K2 articles, I think the discussion should be created just after a first post to avoid create a lot of discussions in the forum without any real question. Also I think is missing an option in the plugin to enable the polls.
