Get Together
Larger Clubs (Allow more than 8 people, maybe 10-14)
Custom Club Officers - the Player/Club leader can create and grant other sims titles, allowing sims to have authority, certain responsibilities, privileges within the club.
Club Account/Membership/subscription - The club could require each member to put money into the club. In return the Leader or Club Officers could use their funds to maintain their Club Hangout. If a club member needs help they can tap into the funds like a loan/grant.
I have clubs that are philanthropists, and it would be cool to see them put money towards events, or help sims in need and issue grants, scholarships as a club.
+ Vampires
New Club Perk: Dark Gathering - Purchasing this Club Perk would amplify your Vampire's Strengths and reduce their weaknesses, during club Gatherings.

New Club Perks: Spell Bound - Purchasing this Club perk would Amplify Spellcaster's Spells, Potions, and Hexes last longer, and reduce the potential of Overload during club gatherings.
