I have few suggestion to improve tours
1) Remove all permanent awards and make them timed for 2 or 3 months
2) Make topic for tour at least 3 days before tour, for more peoplle to see
3) Use channel topic for information about upcoming tor
4) Award first 2-3 players (depend on amount) with lower amount of psr and announce their name, so more motivaton to participate even if you know you wont win
Some was sugested in another topic, i just put in official form as suggestion
