Leadership at psd-turorials

After reading about leadership in online communities in our book and thinking how we could manage this in our own community I analyzied how this is managed on psd-tutorials.
There are two administrators on psd turorials. They release tutorials or downloads, support members when they have questions about their accounts and have basically all functions for conception and programming of the community.
Beside the administrators there are also moderators. The moderators are responsible for the different subject areas in the forums. They have special knowledge and skills in the different sector and have a look, that the threats are posted in the right forums and topics and sometimes there give also advise and help.
Before you become a member of psd tutorials you have to agree on certain terms of conditions. One of this terms is a good spelling with capitals and lower case letters. I recognized, that when people use a wrong spelling or use only capitals/lower cases in their posts the moderators point it out. If someone does not stick to the rules, posts or also memberships got deleted and blocked.
