Danielle,
If the organization you're working with is on a supported copy of Raiser's Edge, you can find documentation on Blackbaud's web site. They also offer online trainings.
Blackbaud offers a listserve for clients. Perhaps you can post there and find a nearby organization that can help you.
There are two RE listserves outside Blackbaud, the
Blackbaud User's Society and
the Raiser's Edge Users Forum on Yahoo Groups. The Yahoo Group includes a Files area where people have uploaded training materials. These forums are also good places to find local Raiser's Edge sites.
You can also look at
this TechSoup discussion of Raiser's Edge training.
Best of luck finding training.
Robert
