Ask for text

I want my NSIS script to ask for a string from user.

This string will be an email or a domain name.

And I want an exlusive choice too:
- Available only in localhost
- Available in LAN
- Available to everyone

How can I do this?
I have some experience in NSIS.

Thanks.

You can create a page with Edit control and 3 radiobuttons with the help of HM NIS Edit or Eclipse and InstallOptions. You can also use Pavonis and NSDialogs for custom page creation.
