Hi liuj66,
I'll fix that broken link. As far as seeing the service, click on "activated" within the service explorer. That will show you all locally installed services regardless of wether they're actually available on the distro server.
Lemme know if this works, as an aside we have a looong list of desired improvements to the explorer web app... so holler with your own requests. after we get this next iteration of the platform out we'll have to steal some time to make that thing more intuitive and useful.
best,
lloyd
