[xwiki-devs] idea: announce plugin

Hello fellow developers, for my local association (Scouts de Forbach), I've been pushing to get an XWiki which is now deployed and starts slowly to be used. One of the central objectives is to get a communication channel between the members. A forum could be sufficient but a wiki is useful already per se. For the communication, I could go in the direction of the message-board or the emerging discussions' module but I am thinking that the threading is not the most important part but the delivery and making sure that people read it. Thus I am thinking of an "Announce" class whose objects would be added by a menu and would first show a dialog inviting to indicate recipients and send the email. Once sent, the announce keeps a track of the version number and the users and emails that have been sent. The email sent is in html, contains the whole page content, and contains a tracker image, individualized by recipient. The image pull, which is activated when people show images (I know not all do), would then update the object and show to the (registered) readers of that page that the given user has read it. Considering my experience of a somewhat uncertain communication it seems to be a useful addition to stimulate the usage of the wiki and to enroll people that do not necessarily go there often. Is anything such existing? Can some of you make other suggestions? What would be the way for me to embed such a menu action and the display of the announce space? thanks in advance. Paul
