I´ve been working where I do for a couple of years now and most of that time I´ve been building up various websites that are now finally starting to get used a lot more. Unfortunately they are now being used by real people (I miss the days when Googlebot was my only visitor). This is a good thing but I´ve never had the chance to test any of the bloody things in more than a few browsers.
End result: all the complicated javascript form validation and stuff doesn´t work, I have to disable it to get it working for everyone and then some pillock comes along and starts submitting the forms without filling anything in! SO annoying….
