I think most chat staff and interested parties are aware of Lumberjack at this point. He sits in 19 and a number of other channels and logs them, and the logs are available off my home server, which is currently http://logs.scp.so. He's a direct extension of Drupal and has already had some modifications made by me to make him useful for 19, namely the addition of monitoring bans and kicks. Right now it's the only web development project I have going, and I enjoy when I have an opportunity to keep those skills sharpened.
There is one big feature already implemented that most people don't know about, and that's that he can hide channel logs to all but a specific group, and users can be in multiple groups. It requires registration on the site, which requires you let me know so I can approve the registration. So if you have a channel you want logged and want a group of people to be able to access the logs, let me know and I'll help make it happen.
This thread is mainly for Q&A on the bot and for requesting features. Two features I'm considering are a "text-only" mode for easier copy-paste, and the ability to look at one user's full chat history. I don't want to go ahead with either until there's at least a couple people that think one or both would be useful. Anything else you'd like to see, let me know as well.
EDIT: Lumberjack has started logging the SSSC by staff consensus. To access the logs, please first register an account at http://logs.scp.so and then send me a tell or PM with your username, I will approve the account and give you access to the logs. From then on, you will be able to see the SSSC logs so long as you're logged in.
EDIT 2: It should be pointed out that having the logs from SSSC should not be taken as an excuse not to join and participate when available. Please use it to supplement, not replace, your time there.
