The pages on this site have been designed to operate using most modern browsers.
They have been tested on IBM Compatible PCs using Microsoft Windows® operating systems with the following browsers:
Safari 3
Opera 9
Microsoft Internet Explorer 6 and 7
The site will also probably run on Internet Explorer 5 but will not display as intended. Users of this browser are recommended to upgrade to the modern free browser Firefox.
They have not been tested but should work on higher versions of these browsers.
They have not been tested on PCs using the Apple Macintosh operating system but are expected to work on available versions of the above in addition to the Safari browser.
They have not been tested on Unix or Linux operating systems but are expected to work on available versions of the above in addition to the Konquerer browser.
Some of the features on the site use javascript (jscript). If, for any reason, you have disabled the use of javascript these facilities will not operate. This includes but is not limited to the fact that you will not be able to read older articles from TLT.
If you have difficulty with the site using any of these
browsers please let us know at 
If you have access to any of the systems on which we have not tested and are willing to do do we would value reports of success or otherwise in using the site. Many thanks.
