I'm glad that you first ask for advice like Karleto with two t's before violating Zplan and especially misleading hikers. We can't allow everyone to do whatever they want, if he wants to be a marker let him sign up for the markers course in 2012 both are still free, there he'll get knowledge and colleagues with whom he can mark if his fingers itch and his "brush" runs, for more zoomed views he can join the action on Triglav, he'll be good for carrying pitons and cables.
Definitely there are other options for marking viewpoints than Knafelj marking which according to law is used for main paths!
We have tourist associations and LTOs; let him connect with them and install their sign, if he doesn't want to establish contact with local PD as you correctly advised him before me, we also have KPP at PZS (maybe he already turned to it??)
IgorZ I still think it's a shame about missing the fifth day
