PLEASE consider spreading it out over 2 days... Sat AND Sunday. 1. Gives more opportunity for people like myself who WORK at that time! 2. Dropping all 100 in the same crowd is just making an individual rich when he gets 10+ of each! *shrugs* At least make them show up 2 days in a row!
For the second part of your comment, this is not how it works. People are selected randomly with a plugin and the head just pops into their inventory. I see you started playing in 2012. It's not like the DP back in the days where the items would literally be dropped from over the fountain at spawn
Usually the server does not reach full capacity so that won't be a problem. Anyone that has a rank is able to join a "full" server, but to be honest I don't know what the limit actually is, it usually does not reach it though so I expect this time to be the same. I've joined drop parties a few minutes before it even started so it's not too big of an issue. However, if you have no rank I do suggest coming online as far as you can in advanced to ensure that you are on the server
From the look at the voting pages, it seems to have a 700-750 player limit, it most likely will not reach that
