While I can understand your frustration at not receiving a reply after almost 2 months, there may be a reason behind the non-reply. Sometimes people do genealogy on a time-available basis and don't get back to things as quickly as they ought to or want to. There could have been a death or illness in the family (or the person herself could have passed away.) The person may also not have set up their presence here to automatically notify them of replies to their postings and may have actually forgot that they left the post here!
Sometimes (although only very rarely) emails get "lost" somewhere along the line. I once received a reply to an email I sent out to a person regarding business and didn't receive a reply back for 6 months. When I gently chided the person about how long it had taken, they replied saying that they had replied immediately after receiving my original email! (Messages get broken up into "packets" and sometimes different packets get sent on different routes to the destination. When that happens, all of the packets wait until "everybody is there" and are then reassembled into a message. This kind of a delay is very rare, but can occur.)
That said, don't give up on them completely. Click on their name and I believe you'll find an email address that you can use to contact the person directly.
Good luck.
