So I’ve finished up the comments feature of the website, and it appears to be working properly. Currently, I have it set to allow guests to comment as well. It seems to be rather good.
On a related note, viewing a post is now in its own separate page, as opposed to a parameter to index.php. I think that it looks a lot better that way.
More features to come soon.
Oh, I almost forgot: This website should be fully XHTML compliant; I have not checked the new pages, but up until this point the entire site is good. Standards checks are a good thing.
