Daily Quest(s)
Suggestion
Something setup where you go to an NPC at hub and punch them to get the daily quest (slip of paper). Randomly gives you a quest. For example: catch x-number of a certain type of fish before the next server reset and return them to the collector (i.e. punch the npc a 2nd time) and get some kind of token reward like a low stat (vendor trash) fishing pole in this example plus a little bit extra xp or maybe a night vision potion shows up on your claims command or something. Just a little something extra to do apart from the vote system to give people a bit more incentive to log in daily and do this stuff and not just log in to AFK farm or whatever.
