Proposed wiki changes

Here are some proposed wiki updates. Discussion welcome.

As of 12-2-09 Noisebridge wiki is running MediaWiki: 1.11.2.

Update to the most current (1.15.1 currently). This will allow image links to work, and wgEnableMWSuggest to work.

# Enable suggestions while typing in search boxes. See http://www.mediawiki.org/wiki/Manual:$wgEnableMWSuggest
$wgEnableMWSuggest = true;

# improves search functionality a tiny bit http://www.mediawiki.org/wiki/Manual:$wgAdvancedSearchHighlighting
$wgAdvancedSearchHighlighting = true;

# Tells Mediawiki to use ETag Headers, decreasing irrelevant page loads. See http://www.mediawiki.org/wiki/Manual:$wgUseETag
$wgUseETag = true;

Poem Extension (http://www.mediawiki.org/wiki/Extension:Poem). A useful kludge giving you the <poem></poem> tag. Inside this tag, a single carriage return behaves like a single carriage return. This makes copying and pasting many text documents into the wiki less of a bother.

The Category:Events page says "(Wouldn't it be great if there were a gCal mediawiki plugin so crossposting wasn't needed? Do you know of a good one? Help us!) <- working on this, need to upgrade Mediawiki in order to use some plugins." What extension would enable this functionality?
