I been around for a very long time and have seen forum come and go.
Also seen topics vanish when there has been a forum update.
Then some times good topics that works as great reference with complete solution are destroyed.
Now i search for saving web content as PDF.
There is different sites that allow you to put in the link to the site and page and download it as PDF.
But is not working with all sites/forum.
Then i read about Google Crome Future - you just browse the page and click on print and pick as PDF and you get your document.
I just wanted to share this.
