mine is when my sister and i used to play when we were little kids in elementary and we would make guilds, make layouts, sites and try to get members...
and the first guild we ever made was really lame because we wanted people to join so we made like 40 accounts and made them all join the guild to make it seem like we had a lot of members.
but it was actually only me and my sister (lol)

we did have much more successful ones later on though once we figured out how to code and photoshop (we weren't completely sad people!)

good old days.
