Thanks again.
re: the SDK - unfortunately, while it looks absolutely jam packed full of good code snippets etc, there's no way of searching it as a non-programmer!
Generally speaking I quite often know what I want to do, and have a fair idea how to, but the SDK site is (well) organisationed in a way that means you really have to know what you're looking for in order to find it.
This thread was a good example - I fairly much guessed I had to convert it into a different format, but didn't know from what format, to what format, and what the commands would be. If I had the ability to search the SDK site for mentions of "convert" I'm sure I would've been able to find something that gave me enough of a headsup to work it out (and I prefer to do that!).
So there you go, a new feature request - searchable SDK\Help sites!
PS I'm sure the script repository will also help. :)
