Anybody heard this optinaccelerator.com?

The script they made can be used to import contacts from address books of major webmail providers for use of tell-a-friend script.

My question is is that effective?

If it is, I want to have such capability on my site. Is there a free script or a script that can be modified somewhere that can import contacts from Yahoo address book for example?

I don't want to purchase this optinaccelerator as I think it will be expensive.
