If I found a question on SO that may should live in another site, I can "flag" then say "it does not belong here". However, the site list proposed only show few  sites of the network.

For example, if I want to suggest a moderator to move a question to sharepoint.stackexchange.com, what is the proper way to do this ?

Concrete example with [this question](https://stackoverflow.com/questions/6439227/listfielditerator-update-item-in-sharepoint-2010)
