Forum OpenACS Q&A: Re: sdm.openacs.org is having problems
However, Google has *many* links in error that reference sdm.openacs.org. Maybe it would be a good idea to redirect sdm.openacs.org requests to the appropriate location on openacs.org?
From my experience, Google's search capabilities blow away the openacs.org search capabilities. So, I believe it's worth the time and effort to make sure that Google's result links land in the right place.
