Imagine that we could write on the trees something like: Mary+John=<3.
For nobody to complain about vandalization of trees or whatsoever more it could be a temporary wood engraving that could last for one Glitch day (for example).
But if it was be offensive, staff would go crazy. That's why we have guides! xDJk, we'll need some sort of amends to this idea, like have it last an hour?Wait, this idea should apply to wood tree's only for a while, and that would help them stay in the market. :)
People would get mad if after engraving something someone (by mistake or not) would harvest clear "their" loved tree.
If for wood trees only then TS could also introduce this idea in one "wood engraving day". People would get badges for engraving stuff and offering to their friends or to give as acts of random kindness. Idk, something like that... :)
