Of course, anyone is qualified to throw a party. But here are some hints about throwing parties that I have learned through my attempts.

1)Choose a day that the majority of people would have off, such as a weekend, or maybe a holiday.
2)Choose a date that is far enough in advance that everyone has time to see the post, check their calendars and respond. I usually pick a date that is at least a week ahead of when I post the party announcement.
3)Don't forget to post a time, and the time zone. I like to evenings, since the majority of players are available then, most will have already eaten dinner and such. And, don't forget, we have pirates from all over the world who play and party, so it's very important to post the time zone.
4)well, you already have a realm posted so please ignore this one.

I also find that's it's a good idea to make sure that there are no other parties occurring on the same days as yours, and that your party has something unique about it, whether it's the meeting place, or one of the planned activities. But, don't try to schedual the party activities too much, these parties tend to just drift off into the spiral, and whatever happens, happens.
