Do you need to challenge clans, or does clan leaders come to you ask for fight? It goes both ways like Danny said, though I had a good amount of time when most of my fights were by clan officials who asked me through IRC. Is it easy to find fight? Not if your looking for a week prep, there are less clans busy when you ask them on a weekend. During the week, it get's harder. Also it depends on what clan you want to fight, if you step up and fight clans above you, that clan will most likely accept. However, if the clan you want to war is below you, you will mostly get declined (unless they have balls to step up).
