=== Complex Tool Authorization ===
The original model where any person can authorize any other person (so-called "viral authorization") works for simple tools, but it tends to fall apart for more complex tools. Important information can get lost as authorizations spread from person to person. Area Hosts and persons experienced and active in the area have, in many cases, worked to develop standardized curricula or checklists for authorization. To this end, a number of tools (Bridgeport mill, Clausing lathe, SEM, TIG welder, knitting machines, etc.) limit the number of people who are capable of authorizing. In some cases, the Area Hosts have established prerequisite authorizations for tools. E.g. the Bridgeport mill and Clausing lathe require the "Tier 1" cold metal authorization; this guarantees mill or lathe users know how to use non-precision tools like the band saws necessary to shape metal prior to precision milling or turning, and it also introduces the user to safety information and metal cutting theory.

Some tools have limitations on function or materials. The SEM user authorization doesn't include use of the EDX detector. ShopBot users generally are not authorized to cut aluminum, and only a small pilot group is doing this until we can develop safe procedures.
Additionally, certifications never expired. A person certified two years ago on a machine who never used it since may have forgotten much of the material from the certification. Although not implemented, having currency and re-authorization requirements (e.g. your authorization expires if you haven't used the tool for 6 months) may make sense for certain tools.

* Limitations on permitted functions or work materials (e.g. a level 1 authorization allows machining aluminum, a level 2 authorization with additional requirements is required to machine steel.)
These additional requirements must be communicated to the membership via the wiki or some other means and may be modified by the Board of Directors or an Area Host responsible for the tool at any time.
