I think every administrator takes a different approach to creating a successful, thriving community. What have you done to make yours a success?   A basic summary of what I have done:   
[*]Found my niche. My niche is one that (a) is underdeveloped by other administrators and communities (b) I am extremely knowleadgeable and © I can offer something that others cannot.	
[*]Started effective social media campaigning with an outreach of over 10,000 users in my niche.	
[*]Sent in an order to the printing shop to get T-Shirts with our logo on them.	
[*]Spoke to influential real-world people in my niche, and got them to push my link/name.	
[*]Compiled a staff of motivated, talented individuals with great people skills.	
[*]Made it so my "work time" is ALSO "play time". I enjoy what I do and have fun doing it.	
[*]Never gave up. Sure, I hit dead spots ever now and then. But perseverance is key.
