ijji doesn't seem to have much events too.
I remember the time where tlunia celebrate valentine days by giving a fixed number of participants chocolates, restore stone, unicorn ( rare % ) , bank vault etc etc daily.
The catch? Go to a certain website, write a love 'letter' which will be sent to your friends (receiver) email. So before 12 midnight, everyone was camping at that website with multi tabs of filled letters. I've never got anything outta this though. Was too fecking slow :l.
