I have to disagree. I think that joining the clan should be getting to know the people first etc. etc.
Not just join the channel ask for test and getting in in less than few days.
Personally I've been around the channel for few weeks until people started asking me why I didn't join the clan. That then means you are ready to join a clan for a reason, not just
because only you want it.
Conclusion, it's good that it is not easy to get in.
