Since I posted this thread three days ago and haven't got a reply yet, I have to presume that I didn't make my doubt clear enough to get a reply.So, let me put it in a proper way.
I have been reading the" ask the teacher" section carefully.
It is much like a book to read where I find new things to study.
But why the number of threads to be viewed is limited by time. A thread which is posted today will not be available to view after two months(to the best of my knowledge).
Is there any other way to view those threads?
"Search" facility is of some help but we cannot search something that we don't know.
Thanks in advance.
