stimpy: UUNet is still advertising UUDial Solo packages on their web site. I still have this package. In light of that, I'm not sure why you say they don't offer individual accounts.

GRIC: I tried Earthlink last year and they had a free add on called GRIC. Is that what you're referring to? If so, it didn't work at all from the Netherlands, their e-mail technical support was inadequately capable to get me up and running, and they kept telling me to call tech support in the US to resolve the problem. A wholly unsatisfying experience.
