well my doubt is:

I want to make a ruby program that number in a URL and checks if the url  
has a forum. for exemple :

puts(“enter an address”);  
endereco =gets()  
@forum = “/forum”  
system("firefox "+ endereco+ @forum);

the code does not work, it opens the page with the site but the variable  
@ forum runs only after I close the open page, and as command not found  
(like I try to use the command / forum)

how can i put it all together and make [url.com](http://url.com) / forum?

PS : Sorry for my spelling errors, I’m from Brazil 😃

gets() retains the newline when the user presses enter  
try stripping the newline (endereco = gets().chomp)
