I killed Essay: Bases and Essay: Graphs & Functions. They were stale, the writing was completely off, and it didn't delve into the subjects deeply enough. Perhaps I'll remake them some day. I also linked to Games. Yes, I realize that there isn't much there now. That will change. At first I thought it would be a good idea to make the whole page first and then release it, but it obviously takes more time to complete than I thought it would.
I rearranged the navigation bar a little. I hope it makes more sense now.
