Currently I am looking at what to do with users who don't have Flash installed on their computers.

During the recent upgrade of the pictures stuff we switched to using a Flash uploader. This was chosen to allow us to develop using AJAX methods, so that when you do an upload the page changes without you going forward through the site. This also allows the user to do multiple uploads and show a progress indicator.

Sadly under the assumption that most users would have Flash installed to watch YouTube clips of skateboarders messing up I didn't code anything to gracefully tell a user they don't have Flash installed. This came up through Feedback from one of our users telling us it didn't work anymore from them. I was a little dismissive of the situation at the time, but on further investigation I think the way it works if you don't have Flash currently is actually quite bad, so looking at sorting that out.
