Where should I submit an error report for a Wolfram Alpha result?

[info7 (Luke Mackenzie)]

The results of a search for ‘Cookham’ incorrectly state that Cookham (a village in the UK) is in Buckinghamshire when it is in fact in Berkshire.

How does Wolfram decide this and how can I have this result changed?

[wolframcommunity (EDITORIAL BOARD)]

At the end of every Wolfram|Alpha result there is a feedback form that wold take your comments and link them directly to the result in question.
