The UFPAC is the United Federation of Planets Award Ceremony.
The event is held roughly every 3 months and awards members with rank advancements, as well as medal achievements. It is also used as an opportunity to announce important events or discussions within the UFP and allows members at the end of the event to have the floor should they wish to bring any subject forward with the community.
I'll be able to pop in for a little bit (maybe) during the pre-event, but my work shift begins at the same time this does, so I'm afraid I'll have to miss out this time.
