I LOVE that my neighborhood is a tight-knit one that shares messages and announcements via notes. That being said, we tend to accumulate a TON of them on the ground, including introductions and community announcements. Thus far some of us have volunteered to be community trash-glitches and pick up expired/out of date announcements (not personal notes-we still leave those for the owner to address). It would make things a lot easier if we had some sort of bulletin board at the entrance (even if its a big tree we can tack notes to instead of a bulletin board, as a corkboard may look out of place in the middle of a housing community).
