Ohay a poll.
There's something in the rules about it, isn't there? At least, there should be.
I'll leave this up, but tbh, there's no good way to get rid of the older clans. If we do a poll and a lot of the members don't like a specific clan, they could kill it out of spite. The requirements had you pass a poll once, not sporadically throughout your lifespan.
I have an idea of what I can do to take care of "dying" clans, but it's going to take some time, and I have a lot of college work to take care of.
