Are you resident in Britain and thinking of making an online claim for pension or welfare benefits? That’s fine as long as you are running the Netscape 7 browser under Windows for Workgroups 3.1 on an IBM-compatible PC with an Intel 80286 processor. Anything more up to date and you are left with no options other than parchment and slate, with applications signed in your own blood.
I exaggerate a little, but the computer systems used by web developers at the Department for Work and Pensions are so decrepit that your online experience may be lacking if you run anything newer than Internet Explorer 6 or Firefox 1 under Windows XP. I am not making this up.
Who needs W3C standards when trial and (mostly) error will do?
