I know it's been suggested before, but since everything's been changing round here lately, I thought I'd try again.
Please, please can we have some more obvious way of distinguishing the WP.com forums from the WP.org forums. I know there is the sticky thread which is great, but hardly anyone reads it before posting. And lately there have been a LOT of posters in the wrong place. I just checked the WP.org forum page and there's nothing over there that even tells people WP.com exists, so it's not surprising that so many WP.org users end up here without knowing the difference.
I really think that it would help to have something more visually arresting on the forum page (that you don't have to click on to read) to make it clear that this is not the WP.com forum, and maybe even a direct link to the WP.org forum. Also, it would be great if the two sites didn't look so similar - different colour scheme perhaps? - so that it would be easier for people to tell that they were in the wrong place.
