It wasn’t immediately obvious if I can use the website to change an existing website, despite the appointment letter suggesting that I can. I used the session searcher instead.
The appointment search process worked well, as did the personal details page, though one of the cardinal sins of web form design was implemented; the ‘place a terms and conditions tick box below the submit button’ sin.
In Luke Wroblewski’s post about web form design, he sets out a number of best practices. The first is that a user should “only need to move in one direction: down”.
Whilst the blood.co.uk site confirms to this, it’s always worth making sure that all the mandatory fields and options appear above the form submit button.
