>I guess I didn't make it very clear, it is only Skype _Chat_ which we are looking to log, not actual voice recordings. Most of the products suggested do voice recording.

I know I've set mine to keep logs forever, but I can't read them with anything else but skype itself, which sort of sucks. Most of the registry entries for Skype, the interesting ones, are encrypted, so I don't even know where does it keep its data. Could be anywhere - today's disks are huge forests.

But there's a COM interface for it:

osk=CREATEOBJECT("Skype4COM.Application")

..and any one from other Skype4COM interfaces. Somewhere in there you should be able to find an interface, maybe an eventhandler() or a prg-based classes with Implements clause (try with Object Browser)... one of those should be able to get you there.
