I am from India. As far as I know, if my friends don't already have a twitter account, they won't be able to follow me. Is this true.
I also wanted to know how to create twitter account through mobile phone. And whether to use India's short code (is it 5566511) or the international number.

Hi, I am from India.
I am having an account at Twitter. I am planning to send updates about our organization to all members.

Please reply to following queries:

Can other people in India follow me using their mobile phone, even if they are not having account at Twitter.

Can I invite other persons from your website, or do I need to SMS each one of them.

Does one needs to visit your website for registration, or can it be done through mobile device as well.

Please guide me with proper procedure as well for above mentioned activities.

Also, please advice if MTNL and Airtel are responding to Twitter number in India.

Thanks.
