As such pages show up in the RecentChanges of the two wikis this should allow communication between wiki communities which is very difficult right now.
FailingRevolution tries to explain the motivation of this feature.
It should be very easy to provide PersonalRecentChanges? with the same technology.
I started an implementation that uses an central XmlRpc server to collect the changes and notify the wikis of new changes that are of their interest. See MoinMoin:AdoptedPages for details. -- FlorianFesti?
Wiki communities could open an embassy page in neigboring wikis that do not support ExtendedRecentChanges. This page would serve as communication medium and be used like an WikiHomePage of an indiviuum but for the whole community.
It is. It is a special usage of filtered UnifiedRecentChanges. The difference is that I don't want a central UnifiedRecentChanges page but integrate it into the local RecentChanges. And I want the whole wiki to share the same selection of shown pages in the RC. I think that unfiltered UnifiedRecentChanges are not that usefull because the traffic get to high and you don't have a shared topic over all the watched pages.
The difference to UnifiedRecentChanges is more a semantic one than a technical. -- FlorianFesti?
