Lots of improvements over the past week or so and many to come yet. The language stuff is taking longer than I thought because as I go slowly through all the code I keep noticing things I could improve and I get diverted! A course that I'm using Moodle for has also started, and working on that is also helping me come up with ideas.
For those of you using CVS versions, be careful - I'm going to be combining the discussion module into the forum module - which will make discourse a lot simpler, but which *may* break sites using the discussion module. I'll try my best to make the auto-upgrade process take care of it all though.
I'm aiming for something I can call version 1.0 (beta) by this weekend.
Looking forward, congratulations.
Just found the Moodle project and it looks great. Hopefully I will be evaluating it for our environment soon.
