May 2017: New KB Wiki Launched

The wiki now has all content available to everybody without the need to log in. The distinction between Gold, Silver and Silver-plus articles has been removed.

This wiki is now hosted on newer hardware with more up-to-date software. It should be regarded as being in Beta-test until the end of May 2017, when the old server will be switched off. If there are any difficulties encountered, the old site can be accessed via the link in green text at the top of each page. Please direct any queries to the administrator at ellacott@ellacott.plus.com.
