We are glad to be able to announce that comments are back! We had to switch off this functionality some time back (and lost all old comments), as we got spammed by it. Now that we have profiles under control, we can switch it on again.
How to do Comments
Comments are allowed only for portal pages of the "article" type and for users with personal profiles (pseudonymous or not)
If you are logged in with a personal profile, you can leave comments on article pages. Comments are for short, personal remarks, stuff like "I really like this", "You forgot ...", "But please consider...", not for substantial replies. For such replies, rejoinders, commentaries and criticisms, we have the "reply-to" button which creates a new article and arranges them into threads.
