It would be great if Confluence supported more forum like discussion capabilities, i.e. very thin subject lines for each thread topic that then link through to the full thread - like traditional forums.
It would be ideal if comments could be turned into forums at a page level as a page option and it would also be great if discussions could be held either in place of comments or under a seperate tab (if discussions were turned on for the page). Customers have requested both alternatives during discussions.
