I agree with you about the seriousness and heft of POSIX (and I definitely know your name from comp.lang.c[.moderated], so I respect your opinion); however, there is no arbitrary gate-keeping around POSIX. If anyone is willing to put in the time and effort, they're welcome to join. This couldn't be more different from other standards orgs where you can only join as a (voting, or observing) representative of an employer that pays an exorbitant yearly membership fee.
