I'm new to this blog. I found this blog a very usefull guide for expetriates. What I personally think that people do ask questions and once they got the reply which is usually descriptive enough to resolve their queries, they don't feel to ask again for more description. I do agree with your point that a person should reply atleast to acknowlledge that he's got what he was looking for.
Please continue your profounded efforts in resolving queries for expatriates. Jazak Allah Khair

Sometimes they reply to the email notification they receive. They don't realize that they have to come and reply here in the website for it to be seen. (Admin)
