When someone with a newbie flag under lvl 10 removes a light, have a warning echo, "Humans, storm giants (etc) will need a light to see in dark areas or after sunset."

Also, it would be player-friendly for those with a noob flag should to detect invis while a ghost.

Sell potions with a short shelflife to newbs that have l_desc like "Cures blindness and constipation." and "Good for avoiding ex-wives and angry lawyers."

When teleporting using a noob_potion, have it echo the area the noob has landed. "You sense that you have transported to what some call the Ashes of Nowhere. Now look at your damn map."

Consider giving noobs a teleport potion (that rots over time) with their standard outfit gear.
