Umm..i didnt think at that but no problem i make this events for people who really cares
He could change location, make a private chatroom with everyone from the event in it and choose an unpredictable location that he found before hand?
thats a lot of trouble to go through, which could easily be wasted cause of 1 dick ... am not trying to discourage you or anything, heck i'm all up for this, especially since i too miss out on all the events due to my timezone... but ijs. .. ik, but how will you keep the ones that don't care from interfering ? .. and how do you really know if someone cares lol, Also for public events, you don't know who has who on their friendslist .. even if you change locations, won't be hard to track it down. easy to do if the turn out of participants are less than 5-10... and you know for certain that none of those 10 are a douche. ... .. that could work if it's a faction event or w/e, .. not for a public event... it's not practical to invite every single random participant to a private chatroom and be sure that none of those that are taking part are in someway assisting the douche, by giving up info, etc... sorry for sounding so negative and shit, but.. i'm just saying what could go wrong and what has gone wrong many times in the past for others who tried to hold such events before.... so you can come to some sort of solution before shit hits the fan..... this is not the first time for someone trying to make such events, and hardly any of them in the past were successful, most gave up due to the amount of frustrations caused by all the QQ-ers and what not when shit don't happen on their favour.
I like these ideas. Perhaps there may be a GM online that can help you in case some people decide to ruin it.
