I would, but I usually have to wait an entire day to post the logs in pretty form.
Why would you? You probably know the original log URL if you can paste it on the forum and the log URL is all you need to make a prettified log.
Try posting a log from a game you just played into a prettified log. It doesn't work until the game is updated into the goko log section, and that takes 24 hours when the thing refreshes.
Nope, it works just fine. Go to any prettified log, copy-paste the raw text log URL into the top box, and hit Enter.
The log-prettifier is all rendered on the client side. It tells your browser to download the given URL, then does some Javascript to make everything pretty. That's it.
