I decided to change my preferences using BAM!. My old preferences had not propagated to BAM!, and neither will the new preferences propagate out. I would expect these preferences to propagate normally once a host contacts BAM! but this does not seem to be the case. Due to my sometimes contrary nature I refuse to hit the save to project link.
The prefs aren't updated from BAM! directly. Currently there is no RPC for that. The prefs must be saved from BAM! to the projects and then the BOINC Manager must update from one project.
In a similar vien I changed teams on one project via a link supplied at a BBR forum. I am still seeing the old team here at BAM! even though I would have expected there to have been enough communication from their server to my host to your server to make the change.
Team info is also not updated from the BOINC Manager. I think BAM! updates the team status on a regular basis so it must be just a matter of waiting
