Is there any way to "auto write/answer thread"?
 

Hello, I was looking forward to make a button in main site, something like button link:

"http://clanheroes.es/forums/newthread.php?do=newthread&f=6"

But I want you press the button and you go there, write "I will assist that event" and reply the thread, automatically just pressing the button.

What kind of link should I place in the button to do that at once? I don't know if it's possible but it should be.
