In the table we see that the applicant actually has more than the required number of sponsors for some languages, but that does not matter. It is not intrinsically better or worse to have more or fewer sponsors. In exceptional circumstances a waiver to one or more of the requirements can be granted. It may also be the case if the applicant can't find two members with the same languages in his region of professional address. The applicant has worked 150 days and probably knows some AIIC members, but to become a member will have to ask for a waiver of the rules regarding sponsorship.
Faxed signatures are acceptable.
Remember , waivers are an exception and not designed to make getting signatures more convenient. Even if you worked together long ago, get the signature. If you can't find sponsors with an A classification in your A language, get people with a B to sign for you. You may add signatures of members who have taken relay from you and can attest to your quality. If you are having trouble even finding people who have taken relay from you, ask a colleague to at least listen to you - and sign stating that fact.
