Links have all just been updated. I removed all the ones that no longer worked, which was only 2 or 3 of them. I added a few new ones to the list as well. I also tried to generalize the links, mostly in the tutorials section. What I mean by that is if a site was linked to multiple times, but they were different tutorials then I combined them and made it go to the main page or main tutorial page.
As usual, if you got anything to add just post them here and I will update the main post for everyone.
