We are currently in the process of putting together a BTU Certified Guide program, to help with JD's question. We will have a page on the BTU website to acknowledge them. Several of BTU's founders are guides, and they are listed on the tarbone.org website: (http://www.tarbone.org/charter_members.cfm)
In the meantime, don't be afraid to give your guide credit - who was it that told you about BTU?
