Yes there are tons of people who sign up for the clan and a good amount of them become inactive. Signing up for a house is the first easy way to say "hey im here and I want to get involved" its a great way to show people that your not one of the hundreds that just sign up then never come back. They help you to find and meet more of our clan, and for more of the clan to meet you.
Its also awesome cause you get to meet the house leaders who will set you in the right direction clan wise, and once you get to know them youl allways have two people you can count on for help and advice.
Basically if you want to step up and plug into our community its the first big step. Check out the different houses, talk to the leaders and members, or send messages with questions to the leaders. See which ones you like, and who you like in them and pick one to sign up in.
