Not everyone who starts a NOBO in Mar. or Apr is a complete fool. But yes some are. So here is my idea. The experienced hikers could do a workshop every evening at the shelter they are at, say at 6:00/ 6:30 /7:00, pick a time so people know what to expect. Just a short little lecture/ workshop on stuff like LNT, digging a cathole with a stick, setting up/ taking down your tent in the rain, other general rain issues, cooking, generic Q&A period, staying warm, etc, etc. after a while these "workshops" would drift away, but just might save some newbies from a lot of pain and trouble. Yes and me being a newbie I'ld appreciate the info.
Nothing very formal or organized, just sitting around sharing info, experience.
