After finding out that Heidelberg's fixes were not in the OpenACS CVS I asked Malte to add them to HEAD. We merged these changes with 5.2 and are now bug fixing together.
We will be cooperating on getting assessment tidy for .LRN 2.2 so please commit any local fixes (not features) you have soon to the oacs-5-2 branch.
For now we are tending towards removing all the options mentioned in my previous post and leaving "New Assessment".
Please complain or fix now, if you are using this untested/broken "feature" and are willing to help get it in.
If we work on it we will fight for just going with 2 or a maximum of 3 different assessment creation options: "New Simple Survey" (as per Bernd's post), "New Simple Quiz/Test", and "New Custom Suvey/Quiz/Test" (this one would give you all the options) for example.
Speak now, or wait for the next release round.
