Aldert,
I can answer you question about .LRN.
Long term we want the groups in .LRN to be created in the most OpenACS conform way possible so that will be used by as many people as possible (e.g. the .WRK group). This way any work needed to clean up the UI will benefit OpenACS in general and it keeps .LRN lean and mean.
We want to keep .LRN as thin of a layer on top of OpenACS as possible, sharing as much foundation with the greater community as possible. As Al mentioned we are working hard at cleaning up the presentation of this kind of information and plan to publish it soon.
