Hi
i have previous experience with mambo cms. i am confident that dnn can do the job - even more. the xmod module may not be able to handle it *or you would have to be a real xmod expert to design forms and templates that will fulfill your requirements (it seems). i suggest listx from
http://dnn.bi4ce.com because this actually interacts with custom tables in sqlserver. (xmod interacts with its "own" tables in sqlserver only). either that or create your own module.
try it out.
