Hi, please use the feedback link on top left of each article, or on the very bottom is a link as well.
If a topic on the forum exists already you'll be sent there and can leave your information. Otherwise it'll open a textbox where you can leave your feedback. It will then create a forum topic for this guide for you.

This helps our content editors keep feedback assigned automatically to the specific each guide.

Just wondering where to post about fixes to individual articles, would you like them on the respective articles forum threat or just in a consolidated thread here?
