Just wondering your opinion on something. Groups of users in our organization want to begin to use Discussion Boards features in SharePoint.

I am pushing that they be created/housed and stored in WSS (Collaboration) sites and not at the SPS level (Portal/Intranet). (My reasoning: because it just feels right to me).

Can anyone offer pro's / con's of if Discussion Boards should be built and used in WSS vs. the discussion boards in SPS?

Technical or opinionated recommendations both welcomed..
