add something like this to section 3
The IASA consists initially of a single full-time ISOC employee, the IETF Administrative Director (IAD), an officer entitled to act on behalf of the IASA at the direction of the IAOC. The IASA temporally may act as the IAD if there is no IAD or the IAD is unavailable. ...
s/The IASA temporarily/The IAOC temporarily ?
Or perhaps you meant the IAOC chair?
