I am getting quite fed up with this system adding random projects to which I am not connected to the Active Projects and Status Schedulers menus on the sidebar. What is the purpose of this function? If it's to try to get me to join more projects, it has failed utterly. All it does is cause irritation and increase the urge to write a complaint "bug" message such as this.
Please look into this. You gave us the option to choose which projects we want displayed over there, so let us make our own choices what to display. Please stop forcing these projects we're not interested in on us.

Are you talking about the statistics link section? AFAIK, everybody has the same projects listed there; they are the links for the stats and project status for all the projects in BOINCstats. I don't know why that would bother you?

New added projects are by default displayed in the side menue. As they are not that often to appear, it's a small annoyance, and once you clicked them away as well in your personal settings, they will keep hidden.

I don't know how much hassle it would be to get a setting in your account that would let you decide whether you want new projects to appear by default, or not to appear. Willy decided to give you more information as default, I can live with that decision, but I'm an ATA

I just tried to adjust my side menue accordingly, and had no success. The retired projects are no longer on display, but the supposed select list of active projects is still complete, not only those I selected. Something's broken probably.

You need to logout and login again to see the changed settings of projects in the scheduler list.
