There has been a WebSphere ESB newsgroup for a long while but it doesn’t see a lot of traffic compared to its sibling Integration Developer and Process Server groups. At least part of that has been due to the fact that they have been mirrored on the developerWorks forums which tend to be the preferred interface for many developers this days (although not myself!) whilst the WebSphere ESB one has not. My colleague Dave Screen has now got this rectified so post your WebSphere ESB questions here!
