Michelle - for your own site, I would agree that's maybe the best way to go. If your site starts making 'serious' money and it's not a standard proposition of sale, I would consider using a specialist in Internet law to review your situation.
I agree in some respects with Stickman's comments and I'm not saying 'don't give your clients examples' - but there is only a subtle difference between this and offering legal advice. If you don't have contractual evidence that you only supplied legal-orientated material as an example (and this goes for any 'advice' that refers to legislation) then you will be leaving yourself open to litigation down the line.
We are a young industry struggling to be seen as professional - in order to achieve this status we are going to have to work a lot harder to draw the line between what we should offer and where we should hand over to other specialists.
Thoughts?
