How to be a wiki administrator
So, you want to help out, eh? Good! We can use some help. Here's some things you could do:
Clean up the wikis
Revert wiki spam, clean out the sandbox, remove duplicated or obsolete data, set up redirects for pages that have been moved, fix broken links, etc. Change notifications for them ain wiki go to wikidiffs at apache dot-here org, which anyone can subscribe to by sending e-mail to wiki-subscribe at apache dot-here org.
Maintain your project's wiki yourself
If you have apsite karma, you can edit the configuration of your project(s) wiki yourself, and even add new wikis. Just take a look at /www/wiki.apache.org/README on minotaur (this machine).
Help other people set up wiki instances and change their configs
If you have apsite karma, you can subscribe to the infrastructure mailing list and help people who send in admin requests. There's no need to announce yourself or get karma or anything like that: when someone asks a question, you know the answer and you can fix it, just go ahead and do so.
Every now and then questions about our wiki(s) pop up on the infrastructure mailing list or on the wiki itself. If you know the answers, feel more than free to reply.
Maintain the master wiki farm configuration
The current wiki is maintained under cvs, inside the infrastructure cvs-module as "wiki-farm". One TODO is to migrate it to the infrastructure svn module. More TODOs are kept in jira: http://nagoya.apache.org/jira/secure/IssueNavigator.jspa?component=10850
If you want to help out wiht this, start by sending an email to the infrastructure mailing list.
