Ah!  Now chad this is also invaluable reminding! thank you for this too.
I'ts late here now but I'm gunna examine this tomorrow and mess a bit with
this, as I've been using stringContains in it's more simplest form, without
realizing it's potential as a function to help return positions of things.
I remember someone mentioning this earlier, and I'm so very greatful for the
code examples you've given as to it's use! I'd never have figured that one
out for myself in a molenium, so thanks to you also for this.
