Talk to climbers with bad access behavior

Here is the 12 year old 8a Access flyers with advices including some specific instructions from The Access Fund in regards Human Waste. As the climbing community is growing bigger, the number of access problems are increasing and although almost everyone behave respectful, it just takes some misbehaving to irritate the landowners etc. Spreading information and creating awareness are important but what is crucial is to actually talk directly to the climbers misbehaving. One way of making this easier, is to post signs at the crags meaning we only have to refer to something "official" while talking to the climbers with bad access behavior.
