I'm currently looking at sharepoint, which is great for inter/extra/intranet. Sure there's document collaboration (which is all alfresco seems to feature), but then there's WCM wherein users can add common modules/web parts, wikis, blogs, forums, calendars, etc.
All I see in alfresco is document management and WCM in the form of html. no modules, no wikis, no forums… no goods. Am I missing it all?
