I have tried installing a message board plug-in and had no success. All too often important details are missing, and the plug-in writer shows every indication he doesn't understand how to explain thngs, that details are important, or that potential users are not telepathic.
In short, sir, I can't read your mind. Even if a step has been explained before, just to be sure, explain it again. So what if it duplicates data, including it in your documentation helps tons.
We're not all cybernetic geniuses, please stop assuming we are.
