I'm not at all an expert of .LRN, but it seems to me, comparing my actual version with 2.4, that all the features introduced by Michele into lorsm has been already incorporated into the new release.
About reporting I found in my version a few additional programs that unfortunately are not internationalized and not very polished.
Chances are that during the next project I will make a better version of the reporting programs, but for now they can be found here: http://www.oasisoftware.com/resources/lorsmreports.tar.gz
Emmanuelle, I installed the head version of lorsm-central on top of 2.4 and apparently it works well.
