I have a lot of stuff on this page, so if you need to find something, you might try searching for it to save time. Otherwise, take a look at the entire page so that you don't miss any of my categories.


I know its still a little messy, but it is a great improvement over version 1. I had started to edit this several months ago, and somehow I lost the changes. Maybe someday I’ll get to revisit it.
