Personal Scrum

I've been aware of 'scrum' and 'agile' for a while; partially down to some experience of software development, partially because my current firm claims to be 'agile' but is still going through the adoption process.
A very useful, and free, tool that works well for scrum is Trello.  So much so, I've been running a personal scrum board for some time; so far, so good.

Trello works in the browser and also has mobile apps for iOS & Android; oh, and the basic (and very functional) account is free.

If you have any kind of list to manage, give it a go.
