please, does anybody know how to:
- connect three mediawiki-wikis through interwikilinks
see http://www.mediawiki.org/wiki/Help:Interwiki_linking
- !!! and modify the search-function that any of these single wikis
searches all of the (three) wikis´ content?
No idea, maybe one of the available search extensions (possibly a modified version of those) can do this ?
