How can I make my clan as request and go clans?

I have seen in many clans that many people come request for troops and leave. Their clans show on the screen of join or search clans. I also want to do so. If anyone of you know how to do it then please write a reply for me. Bit before that please read these points before your reply.
1. My clan name is Royal Rush not the namr req and leave or anyother.
2. My clan is lv2.

I THINK that most people do this don't have it as their main clan. I don't know why anyone would want it as their main clan. But, people are not going to to know if you don't put it in the name. Even then, it will probably be hard to get noticed. There are likely many out there. I just did a search for "Request" and yep there are probably hundreds of them. :) I think you will need a strong network of people to ever get the word out. Good luckl

Thanks for your advice
