PHPBB such as http://www.google.com/search?hl=en&q=phpbbs
You see that PHPBB and Wiki's share a similar idea in user alterable content as well as the attack (security) issues.
It's a lot of work and may be a way to upgrade your code skills in what I might call "trial by fire."
I am about to make an internet site that will involve user's, who can create and manipulate their own web page. I suppose it is a similar setup to that of myspace, but a little less complicated.
I have a strong suspicion that this cant be done with the basic code language of HTML. Could someone tell me what type of coding i am going to need to research (CSS?) and whether there are any free basic codes, that can give me something to build on?
Also, is this possible to do on dreamweaver?
