I am the Clan Master of the SnuggleClub clan, and we are always recruiting active levelers! There aren't really any rules, other than just to be active. My clan is for leveling because I am slowly trying to max the clan passives, and as a trade off for people who help me get clan points through leveling, they receive the 10% Exp Boost passive and are free to stay in the clan once they are maxed and need to get their PVP gear; we have the PVP Offense and PVP Defense passives for that as well.
Note: SnuggleClub is currently only 90 slots and I often add people, so unless told otherwise, I will kick people who have been offline for 7 or more days to make space. if you are going to be gone for 7 or more days, just let me know beforehand or ask to rejoin when you're back ^_^!
