204889 community script

I need somebody who is capable of creating severeal scripts for me. This shouldn't take long if you know what you are doing. I need a script/or scripts which will enable users to log in and create a profile on the website. They will then be able to go onto a forum using the details from logon. You will not be able to post messages on the forum if you are not registered. I will also need a script to be made for registration collecting information I will specify. I would need these details (which will be used throughout the site) save in MySQL. Users whilst logged on will be able to participate in a chat. I would need this creating too don't worry about the design. Users will also be able to contact other members through the website and a reminder sent to the reciever. The other users will not be able to see the other's email address. Oh, apart from create a profile, they must be able to change their profile too. I would need a script to do this. I will create a HTML page with a form to send the variables to. It sound like a lot of hard work, but it isn't. I just need scripts, don't worry about the design. I don't mind what you use as long as it isn't just one script you've downloaded. I will need comments about what is happening at each stage as well as what I need to change to apply the script to my site. any questions, just ask. :-)
