What I'm envisaging is a sort of big red button marked "I have a issue with this manual" that would result in a sort of small questionnaire that could be filled in anonymously. Basically I want the tress-hold for filing issues to be as low as it could possibly go. We have to remember that our target audience here is quite likely not -yet- deeply into our little scene. They may not have a list subscription, for all we know they didn't even yet manage to install ChucK. I could even imagine going as far as having a hotlink in the final pdf that would link to this feature. Right now we have no way of getting info from people who try ChucK for a afternoon, then quit, while that would be spectacularly valuable information.
