Michael: Thanks for your support. It makes all the difference.

Kunda: Thanks for sharing that. I'll have a good look at it sometime soon.

a.l.e: Those screencasts look very nice. I'm still experimenting with LICEcap, on-and-off.

The problem I have at the moment is finding something that will let me trim the start and end off an animated GIF, preferably on OSX, and definitely with no compiling (which I can't do at the moment).
