Build a Website

Hi, I am looking to create a forum-based rpg website? I want to emulate these sites here where you can click on the left sidelink to enter into different forums: [login to view URL] [login to view URL] [login to view URL] [login to view URL] Here is an example of a forum. [login to view URL] On the side of the site, there are other links that users can click to enter similar-looking forums. [login to view URL]: Here is an example of a thread that shows the items that are available on the site. The user "owns" these items in their inventory, and they are able to send and trade items to other users, for other in-site items and in-site currency. The inventory items and money are not real. They will exist only on the site. Some examples include: [login to view URL] and gaiaonline.com. Example in-site items on neopets: [login to view URL] Example in-site store: [login to view URL] Example in-game currency (NP = in-game money on neopets): [login to view URL] I want to include member registration in my site as well where they can only post if they are a registered member. Please let me know if you need clarification. Thanks!
