I dont really have a single best moment, but getting a bunch of people that you havnt spoken to in ages turn up for some games is one of the reasons that ive stuck around for so long, its a good feeling especially since everyones so damn busy all the time and then theres time zones and all that other shit to take into account, if it feels like people have put effort into putting in an appearance it doesnt feel like you have completely wasted your time you know.
