Hi Prasad I sent this off list but it may have gotten stuck in your email filters. I noticed you've been asking a lot of questions about Storm on the mailing list. Welcome to the Storm family! It's great to have you involved and asking questions. However a lot of the questions you've been asking have been confusingly written, often with poor grammar and punctuation. It's also not always clear what you're asking. This makes it hard for people to answer, and most people will just give up if it's too hard to understand what's being asked. To get more answers to your questions, you're going to need to work on making your questions more clear. This site http://www.catb.org/esr/faqs/smart-questions.html is a great guide on asking technical questions and helping you get the answers you're looking for. In particular, some of your questions may be better asked on StackOverflow than the Storm mailing list, at least in the first instance. Thanks, Daniel.
