I updated the site a little bit over the past couple weeks. The first change is adding some links to the sidebar, so if you don't remember that I have a map of the IPv4 address space (or whatever), you can remember by looking over there. Also, some bot keeps posting spam comments, so I've switched anonymous comments to requiring approval. If you're logged in, your comments will show up right away, but if you're not then you'll have to wait for me to flip the switch on them.
