So, a while back we got a challenge from an individual to create a website that would allow people to maintain a small blog on the side of their main blog. Kind of a...sideblog. Ran that site for a few years. Had a few thousand people using it. Yeah, I'd say it worked okay. Oh yeah, the guy who issued the challenge? He works for Blogger now. Nice.

Here's some of the code that made it all work:

display.php
The display script that would show the mini-blog on the client site.

commenthandler.php
The handler script for submitting comments on posts.

atomhandler.php
The script that created an RSS feed of a user's posts.

email_post.php
Code to handle posting to the mini-blog via e-mail.
