I am a little confused as to where my Boinc computing preferences are being set. I have set my account manager to BoincStatsBAM!, but when I look in the Options - Computing Preferences, it states that it is synchronizing with another website: http://escatter11.fullerton.edu/nfs/ . How do I adjust this to be syncing with my intended account manager, which is here? I even dropped my account manager and reconnected, but it is still pointing over there. I am using BOINC manager version 7.16.11 on Windows 10. I can log in there and change my settings, but that is not my preferred method.

BOINC takes the preferences from the last project they have been saved at.
After that they are spread all over your projects so you can change them anywhere.
If you want to use your preferences from Boincstats you need to save them here and not change them from anywhere else afterwards.

Hi - I disconnected/reconnected BAM as the manager after I created and made all of the settings changes I wanted to my host groups/project defaults. Maybe give that a shot? Make all of the changes first, then disconnect/reconnect. I am using the BOINCtasks software (which works great) to manage things with all the machines I have and like I said, the "bounce" worked well for me.
