Advertising for Investors and ASIC rules

Does anyone have any experience or deep knowledge of the rules regarding advertising for investors in a business venture? In my specific case, I'm looking for a better understanding of my obligations as the publisher of a website where businesses may come seeking investors (and conversely, investor may come seeking businesses to invest in).

I recently came across ASIC Class Order [CO 02/0273], which discusses exemptions to the fundraising provisions of the corporations act specifically for those people running a "business introduction service" and not specifically offering securities.

I haven't had time to digest this fully yet, but given how frequently I get asked about these things, I'm thinking it may be worthwhile exploring this further to see if I can allow people to advertise for investors legitimately.

Until now, I've been refusing to publish such things on the grounds that they may be against ASICs rules - but if there is a way I can legitimately allow it to happen (in a controlled manner), I'd like to explore that possibility.
