Hi,
With the publication of the documentation for 6.5, we have removed the possibility to comment on a page. After much deliberation, we decided that it was better to focus all discussion on Bonita BPM here in the Community forum, and not treat documentation separately. (It also saves us the moderation time, which we can use for content instead.)
Please keep your comments coming, here in “Answers” (even if they are questions!)
Chris
