Matthew, I recommend you use assessment on head, b/c there has been some very useful cleanup (e.g. we just committed a bunch of bug and UI fixes and plan to continue adding fixes over the next 3-4 weeks). If you do not feel as adventurous wait for the .LRN bug fix release that we hope to get out in November (we will backport assessment fixes from head for that release -- assessment was included as an untested optional package in the last release).
