So, comments should now be working. All the people who aren't reading this can now tell me what I should have said instead of what I actually did say.
The comment plugin also handles trackbacks, although I have no way of testing this and I'm not really sure what will happen.
I'm not so sure it's really a good idea to open up a place where people will spend all their time talking about me, but who knows, maybe people will be nice for a change. Here's hoping!
