You can find this feature in lots of servers. Only regulars players (if experience suggestion is accepted) could get in. You can use the regular player club for:
- Respawn inside
- Bank and withdraw money
- Get a respawn armour and health (only 1 time per 10 minutes)
- Have duels in a private duel arena
...
dunno what more features could be added, but think about this, i think it would be nice ^^
