Hi Rajesh,
You don't mention website building among your interests. This forum is owned by Coffeecup Software and it has been created for their users. They make software for website building, not exactly business tools for anything else outside of that.
If you want to build a website, you can browse the various apps from Coffeecup Software, and also download trial versions which will work fully for a limited time. If you have questions about those apps, you can ask them here, and we will reply to the best of our knowledge (remember, we are also just 'users').
