This is an experimental WordPress multisite blog that’s been set up to both allow the owner of the blog to create individual blogs for his own use and see what works well and what doesn’t in a multi site environment.
The overriding criteria for this experiment is that as much as possible should be done ‘in house’. As an example, WordPress by default uses Gravatar for profile images, a plugin will be used that allows users to upload profile images to the site.
Another criteria is that the site must be fast loading. If any plugins etc. are found to slow it down to unacceptable levels, another solution will be found to maintain usability and speed.
