92052 Clone for Community MS, Xanga

Hello, I am looking to develop a new community which is similar to those of MySpace, Xanga, Friendster etc... I want something very similar to those but of course would like to see some improvements on the already established scripts. REQUIREMENTS: Friendly Coding and efficent coding- I do not want 5 differnt PHP files if it can be done in 1-3 files. Design should be easily to edit. For example in the future if i decide to upgrade or edit the design it would be easily to do so. For the CMS i require: easy to manage CMS. can arrange advertisements in different tiers. Ie. Tribal Fusion - Casale - Burst - FastClick adverts showing depending on target audience. Can block any website easily, for example, i believe this website is affecting my users i can block there images from appear on my website. Can see useful statistics such as how many profiles are currently online, how many profiles are created etc.. Can see which profiles have not been used for say 1 month so i can post emails to them notifying that the profile needs to be updated or deleted. all the basics of MySpace ie. instant messaging between profiles. post bulletins etc... THE DESIGN- Something nice a simple. the targeted audience is at the age of 15-30 Easy to browse PROFILES LAYOUTS: I would require for user profiles that they are able to input html coding similar to those of myspace to make there profiles look unique. However this profiles mustn't allow them to use any advertisings such as google adsense etc...also the html coding they paste must not be able to block the advertisement banners i have put in place. Also design the script efficient is also important. Since i am especting to espect this site to grow, it would be important to enable to script to run across a more than 3-10 servers. So cluster i would so. Maybe sharing the load such as the SQL data base is on a seperate server to the websites. However at the start i will be just operating over 1 server. Also please try to limit the bugs or if there are any in the future you must fix them. Also secuirty is important. I need to scripts to be done security so people can not hack into my site to steal info or try to mock my site. there is a lot more info i would like to include however there are to many so ask me if there is something you arn't sure about. If you have this script or done it in the past it would be good so send me the script as an example so i would know if your the right one. thanks
