OACS is the abbreviation of Open Architecture Community System and would therefore be fine with me, just TIP it once discussion has settled.
OAKS on the other hand is a nice word, but has nothing to do with OpenACS. This has also an implication for the URL. As all versions of oaks are taken (oacs.biz does not help either though), we would still have to mention Openacs so people can find the website.
OACS => OpenACS is an easy translation
OAKS => OpenACS ... welll.....
