Export connections

I look after, and am administrator for, about 15 medical websites who in turn use Contribute (as publishers) to keep their websites updated.

I've recently bought a new PC so need to move over my Contribute settings.

I re-installed my copy of Contribute 3 (packaged with Studio 8) and no longer have all my website connection details (as I would have expected).

Can anyone tell me where the website connection files are stored (or if there is an export option) so I can copy across from the old to the new machine.
