Thread:Project:Support desk/Making an edit propigate to multiple wikis

I would like to set up two Mediawiki instances on separate servers. I am looking for a way to add an option for a page create or an edit on Wiki A to propagate that same edit to Wiki B. For example, If you created a page on Wiki A and were to check a box at the bottom of the page, on saving, that page would not only be saved to A but also to B. I have looked through the extensions however I have not found one suitable. Anyone point me in the right direction?
