Many people have contributed comments, suggestions, design ideas, questions
(and answers), bug reports, and code to GBBopen, and we appreciate their time
and effort.  Acknowledgment of some of their contributions here does not
necessarily imply that any individual or the organizations with which they are
affiliated endorse GBBopen or this documentation.  Disclaimers aside, GBBopen
users thank each of you!

Douglas Crosher ported GBBopen to \xsitelink{Scieneer

\paragraph{Legacy Contributors}

GBBopen builds upon concepts and ideas that were explored and refined in the
UMass Generic Blackboard system and the commercial GBB product.  The following
people made significant contributions to those systems:
