Well first let me say I have just begun to navigate this oc world was unaware of the alternative site for communication.The "sign issue" is a very big thing here.
A "heads up" can be obtained in many ways: by experience sharing on OCDO, by looking at Friend or Foe , or by simply presuming that you will not have a problem until you do......someone had to take the first step, break the ice.
Gun Buster signs OTOH are there for all of the world to see and thereby help to promote and further the idea that guns are bad. Suggesting their use in fact encourages putting them up. Please don't.
I still am not sure I quite agree with the sign concept as you see it, however I would hope to not offend the forum protocols or let's say philosophy . Thank you for the education I will strive to do my part to follow the guidelines.
