The support community is a voluntary association of people - some of them are Cisco employees and a few of them are even Cisco TAC employees. Most are just fellow users of Cisco products who come here to ask questions and, as they are able, answer them.
It is not a substitute for paid Cisco support which is provided by the TAC as part of a support contract. That has SLAs and is guaranteed to get you problem resolution.
Once an unanswered question drops off the front page of a given forum, not many folks take the time to find it and answer it as we mostly do this on a very part time volunteer basis.
That said, I answered your question in the thread you linked. Hope it helps.
