Uninvited guests are required to pay 10,000 credits. 1km battleship being used as a dance hall, with the largest and most expensive buffet and selection of alcoholic beverages, is very expensive.
Uninvited merchants must pay the above, and if any contracts are done, 2% of the profit of the contract goes to GOMM. (Initial pay of the contract. GOMM doesn't get a permanent 2% every time the buyer makes the deal. 2% per each contract or bill of sale made)
Sorry if this displeases you.
Disclaimer: Any members who were officially invited may make contracts and sales as much as they want without any charges or repercussions. Also, if you are a company hired for the event, you are considered 'invited'
