In '07 we had some great events, I'd gladly show you how they were organized, but those topics are in the Private section of our community forum so instead of give you the link I drop some lines here.
One of the best event was our "Union Screenshot Contest". Every forum user could enter three screenshots, the union (& friends) made their election from the pictures plus the admins chose a special one. If I remember correctly the winner won 1M gold, 2nd, 3rd got gold as well and the special "choosen one" got a D1 SOS Armor as surcharge.
"Relaxing" (by Erinna) won -

You can make the Screenshot Contest more interesting if you set up themes like "landscape", "job", "pvp" and so on.
After Lv.90 cap raise a friend had a great idea of organizing a "Mask Event" which would have been similar to the well known "Kokoru Race" but using Kokoru Mask would have been forbidden. Too bad we have never done that event due to inactivity and ignorance in Union. Although we still had a bit fun seeing each other testing which mob is the fastest, lunatic races between GS and N-Gate of Hotan were great!
These were the rules -
- Kokoru masks can not be used
- Buffs, scrolls are not allowed
- Those players who run out of time or simple cancel mask and reach the end point as character and not as a monster will be disqualified
- Every competitor must donate the race with the amount of gold s/he likes
- Donations will be shared between the 1st, 2nd and 3rd fastest players
This was the proposed start and end point -

Credit goes to
Picazo for the idea of "Mask Event".
There is a new-old idea in my head now, but I would like to keep it for my currently Union and make it public when I'm back to Oasis. Of course you can get to know it via PM.
I hope this entry helped a bit, good luck & have fun!
