I just found this online directory: Minnesota Online Special Needs Directory: Twin Cities Metro Area. It's referenced by the Wrightslaw Yellow Pages for Kids with Disabilities (MN).
It's published by Jenzi Silverman at the UMN Dept of Educational Psychology. It's very plain -- there's not even notation of last revised date. I don't find the organization terribly useful, it's crying out for an embedded Google search box, but it's the only place I found an (obsolete!) link to the interesting Eagan ProAct agency that works on employment skill development.
Clearly I need to create a custom google search for MN special needs resources and show Jenzi how to embed it in her directory page. More on that soon (I hope).
