First notebook entry: Introducing myself

My name is Mauricio and I am studying English and spanish, and I would like to improve my English<em> level</em> with your help, <em>>> (you can do without 'level' here.)>> </em>improve my English with your help

I think this page offers a very good opportunity to get<em> real contact</em> with native speakers.>> <em>(you can say instead 'get in touch with')</em>

On the other hand, I would like to help you with the topics related to Spanish, if you have questions<em> do not doubt</em> asking me. >> don't <em>hesitate to</em> ask me.

 

<em>by the way, I'd love to get your help with Spanish. ^__^</em>

Some other common expressions: How is the weather today? आज मौसम कैसा है? How the weather would be today? आज मौसम कैसा रहेगा? It's very cold today. आज तो बहुत ठण्ड है. By 'touch and go', if you mean to say that it's a bad weather with rain, thunder etc. you can say आज मौसम बहुत खराब है. आज = today मौसम = weather बहुत = very/too खराब = bad है = is

as tushar said, you can say it in both ways -- चलो/चलिए, शुरू करते हैं! चलो/ चलिए, शुरू करें! चलिए is generally used for showing respect to other person or in a formal situation. you can also use आरंभ instead of शुरू, e.g. चलो/चलिए आरंभ करते हैं (or करें)!
