I installed the Drupal module pathauto tonight. I have it set up to automatically add the title of a node to the URL. So what was once
One very nice thing is that either URL will continue to work. The longer URLs are nicer when you are trying to figure out what node a comment is on and are also nicer for search engines, the shorter are nicer when you are typing them in.
I don't think any exist URLs should have broken, but if you notice any that have please let me know.
Mmm... wait, no nevermind. I guess I blew up the navigation. Will get that fixed ASAP. Sorry about that. Fixed.
