Guild Participation?

Any ideas on how to get Guildmates to do more activities as a guild? We have 50+ members but many seem to go their own way most of the time.

Elite missions weekend. (DOA as well)
All master/bonus weekend.
Green Farming weekend.
GVG.
HA guild team. (8vs8 ftw)
Poker.
Be creative.

If you have ideas, ask them which ones they like and put those to use. If you are part of an alliance it might be easier to organize alliance wide activities except for GvG of course.

I know a few guilds who have held dodgeball tournaments, using Me/E's with maxed Fast Casting and Air Magic, and the only allowable skill on the bar being Lightning Orb. Load each player's armor with superior fast casting runes to bring health down enough so that a single lightning orb should kill... And no weapons.

And naturally, a good prize for the winners (maybe a few rubies or sapphires - something valuable that people might want to compete for). Can be a lot of fun

If you come up with something or a guildie suggests something, DON'T under any circumstances let them leave everything to you in order to make it happen. If they want it, they should at least work towards it.
