As we think about how best to organize this site, one question will be the relationship between what goes in the forum and what goes into the groups. While the search and tagging features of this site simplify the process of finding everything on a given topic, I think it would be wise to have some guidelines on where to start discussions.
Let's start with this basic premise:
General topics that would be of interest to the entire community should go into the forum section in the appropriate category (i.e. - CMS). Specific topics that would appeal primarily to a subset of members should go into groups. (i.e. - WordPress or DotCMS).
