w7vss,
We've got a collection of volunteers were selected over the years to mantain certain sections of the database. I've got a list of folks that I'm still looking at granting access, however that has been delayed recently due to so much development work that is occuring.
We typically select admins based on their prior history of submitting information to the database and their participation on the forums and in the community. A lot of times an admin will recommend another person to be an admin since the current admins work with the overall community to make sure that the data is valid.
