Hi,

I get the following deprecation error saying that

!!! DEPRECATION NOTICE !!!  
The WWW constant is deprecated, please switch to the new top-level  
Mechanize  
constant. WWW will be removed in Mechanize version 2.0

You’ve referenced the WWW constant from ./xxxxx.rb:22:in `initialize’,  
please  
switch the “WWW” to “Mechanize”. Thanks!

Sincerely,

Pew Pew Pew

what does switch the “WWW” to “Mechanize” mean? The error is for this  
line  
@agent = WWW::Mechanize.new

Ryan covered this in a railscast. If memory serves, you simply stop  
typing the WWW part.

Respectfully,
