[Radiant] Working through an Extension

Thanks Sean.

That's good to know. :)

Ah, the attr_accessor - I just noticed that that was the part I had 
commented out from your extension.  I think once I put that in, I should 
probably be able to get the string that my user entered.

I just looked at the JS files and assumed it was Ajax - my bad.

Teach me to fish! :)  The ability to add extensions is useful - I'd like 
to learn.  But, seriously, thanks for pointing me in the correct 
direction.  I'm sure I'll probably (that sounds strange) come back with 
a few more questions in the next few days (hours?).  I think it's time 
to get a copy of 'Ruby for Rails' and read up on meta-programing :)

Cheers,
Mohit.
