I'm not sure if it is a question of funding or simply a limit to what the Bulletin Board provider's software allows? Tinox is the Site Admin God, here, and can probably offer more information in that regard.
During the span of time in between the Great Crash of the Old Sanctum (the provider claimed that the entire site's data was corrupted AS WELL AS all backups, effectively destroying YEARS of stories and articles) and the rebuilding of the New Sanctum, there was a temporary site created to allow the community to continue to contribute and stay in touch while everyone waited to see what was going to happen with the Sanctum.
It has a chat feature, etc. However I don't think it sees much use among the community here: http://azeroth-press.enjin.com/home
