I have provided some links to get you started. The titles of these sections
can be used as search terms if you want to find more examples.

You may search here: http://wordpress.org/plugins/

Aim for a minimum of 3 plugins in your report.

Darren - Contact
Bert - Gallery
Andrew - Timeline
Aleks - Blog roll/RSS feed

I have done the header image plugins so no need to worry about that.

-- Blog roll/RSS feed --
http://wordpress.org/plugins/jps-get-rss-feed/
http://wordpress.org/plugins/rss-feed-widget/

-- Timeline --
http://wordpress.org/plugins/wp-simile-timeline/ - similarity to gantt chart may not be what we want, but could include anyway
http://wordpress.org/plugins/ahmeti-wp-timeline/ - looks good, but is in polish(?)

-- Gallery --
http://wordpress.org/plugins/nextgen-gallery/
http://wordpress.org/plugins/gallery-bank/
http://wordpress.org/plugins/easy-media-gallery/ - some features require pro version, note this

-- Contact --

-- REPORT FORMAT --

[Title of plugin] (bold) - [number of downloads]
[Link to plugin]

[Quote first paragraph from the plugin's description page]

[Screenshot of plugin in use (if available)]

[Paragraph talking about the plugin. Talk about customisation options, flexibility,
major features, etc]

[Bulleted list of main/important features]

If the plugin has good or bad reviews it may be a good idea to mention it, especially
if the plugin is popular. If there are few reviews then there's no need to bother.
