A nice idea would be to offer a "synchronize entlistment" button, to allow users the manual affection of the synchronization. Of course, it should'nt be possible to run a synchronization always. I would more expect that after a certain ammount of time (maybe 7 days?), the button becomes enabled and allows a user to accelerate the synchronization, like we can now do by emailing you guys, if we fell our repositories aren't updated often enought.
Btw. could you please sync #6078 and #3315? :) TIA!
