I do believe you are talking about Trouble Brewing. I do believe we had an event there before (agaisnt one of the other slayer communities). If i remember correctly, the turnout was poor (was at work or a hockey game myself). The problem with this minigame is that it requires part of the pirate series of quests to be complete (up to Cabin Fever)? It is a minigame i enjoy playing though, and it would be great to get the nest there.
