Although Web site owners sometimes know how to speak certain languages their pages are translated into, that's not always the case. Realizing that, Google will make the "contribute" function available to visitors, as well. However, the changes visitors make won't go live until the Web site owner has approved it. When owners make the changes, they'll go live immediately.
How can the site owner see the contributed text ? Is there any setting that one has to use ?
