I've been rather intrigued by the thought of creating a website where people can go, sign up, and practice HTML coding and have it reviewed and critiqued by other web developers.
I've talked with a couple friends of mine who are web developers, and they thought it was an interesting idea, but (obviously) there would need to be security features in place, especially if I were to do any more then just HTML code. What do you guys think?
I'm a long way from being ready to design such a site, but I find the thought intriguing and I wanted some more opinions/ideas.
