My personal collection of useful or interesting sites from around the web that I think you should check out!
I try to keep this separate from my "buttons" page which mainly consists of personal websites. This page is for resources, tools, downloads, and sites without a button.
Note: I try my best to make sure the things I share here are safe and trusted, but I may make mistakes. Please keep yourself safe while browsing the web and make sure you research before visiting a sketchy download page. If you find something here that's malicious in any way PLEASE contact me so I can remove it. But that's unlikely.
Also, if any of the links here are dead, please let me know so I can either remove it or replace the link with an archived version.
