One of these days I must read the Sedo rules.
They've got at least 3 ways they suggest you can send traffic. and I was thinking of using a refresh for the index page, but harvesting the typos. I haven't checked if they allow that though.
I'm not sure that Sedo is the best place for parking, some of the others seem to earn more money. I've been lazy and just dumped a load of minor names on Sedo.
