The admins are not (or needn't be) a cabal determining the direction of the project and the site's content. The main role of admins is simply to clean up vandalism, for which they have access to a set of tools that makes this quicker and easier, as well as technical support. In editorial matters there is no automatic superiority of admins.
More moderators may be added, you can volunteer yourself, or recomend others here, requirements are:
- a registered username
- a clean "edit history" and/or history of talk.origins/IIDB posting
