Welcome to ILX Sandbox.
ILX Sandbox is organised as a set of message boards, which can all be accessed from the front page. In addition, there is a site new answers page, which gives you a view of all the recently updated threads from the entire site.
If you want to post, then you'll have to register, which you can do from the menu bar above. Once you are registered, you can customise the site new answers and questions views to suit yourself from customise site new answers. This lets you show or hide certain message boards, and colour them to suit your preferences.
