Few days ago, I added information of aD work of ACES and .LRN to the Wikipedia. You will find it under 2000. I put it there as I was only able to find aD press-releases about ACES dating to this period (On www.archive.org). If any of you are aware of it (ACES) having been deployed earlier, you can correct it there. Here is the text I added there:
* May, 2000: ArsDigita, a Boston Massachusetts based start-up who developed the Arsdigita Community System since their inception in 1997 deploys Caltech Portals at my.caltech.edu [http://web.archive.org/web/20000530235506/http://my.caltech.edu]. Later that year in October 2000, deploy the ArsDigita Community Education System (ACES) at MIT Sloan School. The system is called Sloanspace [http://web.archive.org/web/20010424194535/www.arsdigita.com/news/item?news_item_id=101440]. The ArsDigita Community System as well as ACES in the next few years grow to [http://www.openacs.org|OpenACS] and [http://www.dotlrn.org|dotLRN]
