How do I input "Malayalam(ml_IN) " words?

[Jayan]

Dear All,
I am a new member to rosetta-users.

I use a lanugage called Malayalam in day to day life. I found that 
Rosetta helps to translate applications into Malayalam.
How do I input malayalam alphabets? I have  tools(Madhuri- 
http://bigbnb.tripod.com/madhuri_about.html) which allow creating html 
pages in malayalam. Can I create words in  this and copy-paste resulting 
string to Rosetta? How can see that the translation came correct?

Regards
Jayan
