Hi Marco,
I am really sorry for the delay of this reply. Please find my answers from your inquiries below.
1 - How to disable User banner below Joomla Articles (see attachement, Capture.JPG)?
I've helped you to disabled user information box from your backend > extension manager > plugin manager > content - easysocial > display information box set to "No".
2 - How tu insert Komento comments in ES activity stream
i have configured in komento "integration" (see Capture2), but it not work
I believe there are some misunderstanding here. Currently it is not possible to display the komento form inside easysocial stream since easysocial already have their own complicated comment system and it will a headache for us to integrate another comment system inside easysocial.
By the way, what the settings does is when a user posting a comment inside your joomla article, it will generate a stream inside easysocial and when someone comment to a stream that generated previously, easysocial will automatically sync the comment by posting the comment back to the joomla article previously.

I will pass this thread to our designer to check on the css issue shortly.
