Had a little trouble at first. Turned out I hadn't set my login module to redirect to home page. Once it was set properly it all worked fine. Was a handy replacement and improvement for a module that did this in 1.5.
We upgraded a site 1.5 to 2.5 and completely changed the menu layout and navigation. This made the massive headache of dozens of all the old sites links so much easier and helped with a custom 404 page to boot.
