Just found this on another forum, quite useful: http://stud.cmd.hro.nl/0773253/notusable/blog/the-ultimate-webdesign-usability-checklist/
I agree with the comment on there quite dogmatic in places, some things really arent worth losing sleep over!
Quite ironic that you can't resize the text within IE on that site. Maybe they should practise what they preach!
This website, NotUsable.com, is not designed by me. Giving me the perfect excuse why this website doesnt pass my own usability checklist. But I would love to hear your comments and dont forget to let me know when you can answer the whole checklist with yes!
