General feedback related to the community site, including the wiki, should be raised on the Feedback discussion board. Feedback might include defects (e.g. wiki syntax that doesn't work), suggestions for improvement (e.g. new extensions or functionality), navigation issues, or just "things you like and would like to see more of".
Note that we don't promise to fix any particular issue, but we will be part of the discussion and ensure that feedback is considered.
Discussions related to a specific article should be added to article itself (using the "Comment" tab associated with the page). Please keep comments constructive and impersonal ("I think the article is great but you could make this change" is fine, but "I think you're great and would like to meet you" could be considered stalking!
