Perhaps an issue of performance, but I just noticed the following, which seems to indicate a misbehavior of the OTN forum software in regard to sequentially processing or canceling previous interface events.
While browsing my communications page, I accidentally clicked on a username instead of the subject to browse the message. I realized the mistake and immediately clicked on the right section. It showed the message. However, a minute later or so, the screen refreshed and it showed the user's BIO profile.
