Why would you require a minimum of 3 character search term in the forum if you're selling a product which integrates with K2, a two-character extension? So stupid. I'm trying to find the likely simple answer to my question, but now I have to ask the question, which implies that I have already tried to find the answer in the forum but was unable. I can't find the answer because the forum won't let me search for it!

I have activated the K2 CComent plugin.
I have configured the settings.
But the CComent area doesn't show up on my Articles.
What else could be wrong?
