We display an outdated Browser warning message because we do not have the volunteer support to make the website with every old version of every Browser type under every version of computer operating system.
Our website usually displays very well in current popular Browsers in their most recent versions. If you get display problems from using olld versions then unfortunately we can not support your systems.
For example, in pre Windows 8 IExplorer old version 8 or 9 there are a number of faults with its display of otherwise internationally browser display compliance standards. They are mostly fixed in the later release of IExplorer 10 but that is only available under Windows 7 or 8. IExplorer 11 is only available under Windows 8.
Please consider keeping the most up to date Browser version for your computer. This not only improves your browsing experience but also generally gives you the latest security protections available in those Browsers.
