I decide to set up a chat room in my community. The server is linux. My friend took care of it for me. but he was absent. I have downloaded 2 chat room system, but I don't know how to install them? I know nothing about linux. Can anybody help me? one is flash chat, Http://www.123flashchat.com/index_9.html, the other one is phpfreechat, www.phpfreechat.net. what is more, what is the difference between them? I want to choose one from them.
