Running a Friendica site for yourself and five to ten other people is very easy. But maintaining a much larger server requires some expertise. You need to ensure that your resources are used wisely.
We have compiled a new how-to containing all the information you need to be successful with your public site (one that promotes Friendica by allowing anyone to sign on) or your community site (a server for your club, church, sports team etc). If you follow the advice given, you should be able to maintain such a server without major headaches.
