make sure you have the plugins folder in the eqemu directory with the check_handin.pl plugin..
also make sure you have the Maps folder with the map of the zone you are using in it..(you probably already have this done since you can talk/initiate quests)
so make sure you have :
C:\eqemu\plugins
C:\eqemu\Maps
edit: heres a link to some plugins.. along with the check_handin.pl
