I don't see how there can possibly be a problem with a Foundation staff member removing geonotices on the grounds that they are duplicated by CentralNotice.
I also think CentralNotice is being over-used a bit. While there are circumstances where I could see the chapter making use of it (so long as it didn't conflict with the annual fundraiser) I definitely wouldn't be keen on us using geolocated centralnotices to advertise meetups, etc...
