Here's some really good advice. You need to have a CERTAIN kind of FC. Kind of like genre for movies or books. Some books are fantasy and some people like fantasy but some don't. Let them know what kind of FC it is. Is it a social guild? Does it hold events? Role Play? End game? All around guild? Will you help people? Information is a must, let it be known.

You need officers, 3 - 5 officers, depends on how big your FC is. You also need to realize that some people don't know what kind of FC they want to join and such. Having a website promotes more organized players to join your FC too. People who tend to put effort in joining your FC will most likely stay. Plus, always say something like no drama and etc. Hope this helps.
