There are a few things, some of them admittedly old-skool, that I want my Blog to be able to do. I don’t imagine they’re all that complicated, but here they are:

1. Allow people to sign up for email notifications when I add a new item or modify an existing one – Email alerts, so to speak. I can get alerts when people post comments or trackback or refer, etc. and I want to go the other way on a subscription basis.
2. Similarly, allow someone – at the time they reply to a post – to choose whether or not they want to receive email notifications of any subsequent comments on the same post.
3. Allow [CategoryName] in any post method’s subject line to auto-add to an existing category (which works in email-posting now, but don’t think it does in Movable Type API, etc.)
4. Allow a post-classification and user-registration system so that people who are signed up can see all public and private posts, and people who are anonymous on the site only see the posts that are viewable by general public.

That’s actually about it. I may think of more later, but other than that, dasBlog does pretty much everything I want and need it to do.
