Dear all,

First of all thanks for Mark A.Hershberger for creating this mailing list!
I'll try (as an author of the WikiFarm extension) to make it helpfull.

The WikiFarm extension (http://www.mediawiki.org/wiki/Extension:WikiFarm) is a tool designed to assist wiki administrators in maintaining their sites: single or multiple individual wikis or wiki farm(s). It uses MediaWiki API to obtain information for every wiki in the list and provides some usefull links and statistics.
The extension does not do any DB modification.

The current version has 7 modules:

WikiFarmStatistics - shows the following information for each wiki:
- wiki name (What API returns)
- number of pages
- number of articles
- number of views
- number of edits
- number of files
- number of users
- number of categories
- number of templates
- interwiki prefix, if exists in interwiki table

The following is visible in debug info level only:

wiki URL and API URL
list of wikis for each DB
table prefix in DB
DB name
DB server

WikiFarmLinks - gathers usefull administrative links for every wiki.
WikiFarmChanges - shows recent changes from all wikis.
WikiFarmPages - shows all articles in the project from all wikis.
WikiFarmUsers - list all users of administrative wiki with useful links for each of them. So it is good to have an admin wiki as one of wiki farm.
WikiFarmLog - provides links to log pages. Bots can write to the log, which is useful to trace their work. The log is a page(s) in the "project" namespace.
WikiFarmSearch - search for string in titles and text in all wikis.

+ You can find special scripts for batch-renaming MySQL tables in tools directory.

The official extension page (http://www.mediawiki.org/wiki/Extension:WikiFarm) provides some screenshots and additional information.

With best regards
