Membership in a TEC is open to anyone. TEC membership does not confer

A majority of the SIG Executive Committee, including at least two of
the officers, may petition the SIG Board for approval of a TEC. A
proposal for a TEC must include (1) a petition from at least 50
persons, twenty-five of whom must be voting Members of ACM and also
members of SIGSIM; (2) a budget for the first year's operation; (3) a
set of approved by-laws (see section 8.d.i); and (4) nominations of two

Each TEC shall have a set of bylaws. These bylaws and all amendments
proposed thereto must be approved by the Chairman of SIGSIM, the SIG
Board, and the Constitution and Bylaws Committee.
A Technical Committee may have elected or appointed officers, as
specified in its Bylaws. If the officers are to be appointed, the
SIGSIM chairman appoints the TEC Chairman who in turn appoints the
other officers subject to the approval of SIGSIM's Chairman. Only a
person who is both a voting Member of ACM and a full member of
SIGSIM may be a candidate for, or hold office in a TEC.
Members of the Technical Committee will pay dues, as determined by

be incorporated in a composite budget for the SIG. Final approval of
the TEC budget is contingent upon approval of the composite SIGSIM
budget by the SIG Board. Expenditures and handling of money outside
