Hi Roopa,
It really depends on who is reading the forum, how descriptive the problem is and what the problem actually is.
As this is a forum, browsed by "general public", there is obviously no obligation to reply to any posts.
I think you will also find that the majority of users are relatively new to PHP / whatever, so they may not have the answers anyway.
What I usually do when I have a moderately urgent problem, is to post a question on multiple forums that I am a member of (not all at phpbuilder).
Hope this explains a bit :-)
Jamie
